  • hook up consent scan check to iridium settings manager and created action to simplify that logic

One little thing on the chatbar, should be 48px height given the 16px font.

@molimauro i thought this was consistent with the current dev branch. i'll take another look tomorrow

this appears to be consistent with dev branch.

The scope of this is already quite large, so I think we should improve chatbar styles later

top 2 -dev
bottom 2 -this branch

Strange, the cursor appears different on my screen from dev and this, also the height. In any case no problem, we can track this and come back later, thanks for checking ;)
