Option for number row to turn into symbols with shift

[K4sum1]

Is your feature request related to a problem? Please describe.
When typing, I like to use symbols sometimes. I do have the long press keys for symbols option enabled, but it's more confusing when I can just press Shift on Gboard and just have symbols in the layout of any standard PC keyboard replace the numbers.

Describe the solution you'd like
An option that I can enable that enables this. You would have to be careful in implementing it though. Gboard is smart enough to not switch the number row at the beginning of a sentence where it's capitalized by default. It has to be only when the user presses Shift.

Use case
If I'm typing percentages like 90%, (doing this), @'ing someone, typing dollar amounts like $70, or really using any commonly used symbols, it's more convenient.

Describe alternatives you've considered
I do have the show hints option enabled, but if I want to type a percentage, I know from well over a decade of using computer keyboards that it's Shift and 5. Gboard works similarly, press Shift, and 5 becomes %. HeliBoard, if I press shift, I still have numbers. I could look at the hints and long press q, or go to the symbols keyboard, but that takes longer and doesn't match already established computer keyboards.

You can do this yourself now (next release) by customizing the number row layout, and using a json layout with a shift_state_selector, e.g.

    { "$": "shift_state_selector",
      "manualOrLocked": { "label": "!" },
      "default": { "label": "1" }
    }

    }

So I upgraded to 2.3 now and I'm not sure how to do this.
I make like a sihft_state_selector.json I assume, but is it just that for every key? I'm also not sure how to import it.

I did not test, but it should work if you edit the number row and add something like

[[
    { "$": "shift_state_selector",
      "manualOrLocked": { "label": "!" },
      "default": { "label": "1" }
    },
    { "$": "shift_state_selector",
      "manualOrLocked": { "label": "!" },
      "default": { "label": "1" }
    },
    { "$": "shift_state_selector",
      "manualOrLocked": { "label": "!" },
      "default": { "label": "2" }
    },
    { "$": "shift_state_selector",
      "manualOrLocked": { "label": "!" },
      "default": { "label": "3" }
    },
    { "$": "shift_state_selector",
      "manualOrLocked": { "label": "!" },
      "default": { "label": "4" }
    },
    { "$": "shift_state_selector",
      "manualOrLocked": { "label": "!" },
      "default": { "label": "5" }
    },
    { "$": "shift_state_selector",
      "manualOrLocked": { "label": "!" },
      "default": { "label": "6" }
    },
    { "$": "shift_state_selector",
      "manualOrLocked": { "label": "!" },
      "default": { "label": "7" }
    },
    { "$": "shift_state_selector",
      "manualOrLocked": { "label": "!" },
      "default": { "label": "8" }
    },
    { "$": "shift_state_selector",
      "manualOrLocked": { "label": "!" },
      "default": { "label": "9" }
    },
    { "$": "shift_state_selector",
      "manualOrLocked": { "label": "!" },
      "default": { "label": "0" }
    }
]]

So it's one shift_state_selector per key. Also the double [[ are required as far as I remember, because the parser expects multiple rows.

So I upgraded to 2.3 now and I'm not sure how to do this. I make like a sihft_state_selector.json I assume, but is it just that for every key? I'm also not sure how to import it.

Just go the settings: Advanced>Customize symbols and number layouts>Number row.
And paste this:

[
  [
    {
      "$": "shift_state_selector",
      "manualOrLocked": { "label": "!" },
      "default": { "label": "1" }
    },
    {
      "$": "shift_state_selector",
      "manualOrLocked": { "label": "@" },
      "default": { "label": "2" }
    },
    {
      "$": "shift_state_selector",
      "manualOrLocked": { "label": "#" },
      "default": { "label": "3" }
    },
    {
      "$": "shift_state_selector",
      "manualOrLocked": { "label": "$" },
      "default": { "label": "4" }
    },
    {
      "$": "shift_state_selector",
      "manualOrLocked": { "label": "%" },
      "default": { "label": "5" }
    },
    {
      "$": "shift_state_selector",
      "manualOrLocked": { "label": "^" },
      "default": { "label": "6" }
    },
    {
      "$": "shift_state_selector",
      "manualOrLocked": { "label": "&" },
      "default": { "label": "7" }
    },
    {
      "$": "shift_state_selector",
      "manualOrLocked": { "label": "*" },
      "default": { "label": "8" }
    },
    {
      "$": "shift_state_selector",
      "manualOrLocked": { "label": "(" },
      "default": { "label": "9" }
    },
    {
      "$": "shift_state_selector",
      "manualOrLocked": { "label": ")" },
      "default": { "label": "0" }
    }
  ]
]

I wonder if it would be possible to keep the long press items too. Pasting that below the default items doesn't work.

For convenience these are the defaults from before I did this.

1 ¹ ½ ⅓ ¼ ⅛
2 ² ⅔
3 ³ ¾ ⅜
4 ⁴
5 ⁵ ⅝
6 ⁶
7 ⁷ ⅞
8 ⁸
9 ⁹
0 ⁰ ⁿ ∅

Right, here it is with popups and shift-key functionality:

[
  [
    {
      "$": "shift_state_selector",
      "manualOrLocked": { "label": "!" },
      "default": {

        "popup": { 
          "relevant": [ 
            { "label": "¹" }, { "label": "½" }, { "label": "⅓" }, { "label": "¼" }, { "label": "⅛" } 
          ] 
        } 
      } 
    },
    {
      "$": "shift_state_selector",
      "manualOrLocked": { "label": "@" },
      "default": { 
        "label": "2",
