Adding a new layout for Grid

[lukas-frey]

Now I see the difference
When on ON_TOP is specified it doesn't hide the list

But I expected a grid with all icons by default so I don't have to type in anything

Good idea. Feel free to make a PR and add another layout or I can have a look at it, if you'd like this feature.

However one problem I see is if you have a lot of icons, it could take a while to render it all. Especially since you could technically install every single blade icon set.
