I've searched around but couldn't identify what this checkmark symbol next to my button means (see screenshot).
What's the button's function defined as?
The button with the checkmark has this code:
Go TABGROUPLOAD "HC Default Tabs"
"%DROPBOX%\Dev\AHK\App-Specific\DOpus Default Window Size & Pos.ahk"
And the whole menu-button is here:
Reset.dcf (2.2 KB)
A button that opens a tab group on the first line will be checked if that tab group is currently active (i.e. if it was the last tab group that was loaded).
If you don't want that to happen, add this on a new line at the top:
@toggle:disable
