Customize option feature request or a bug fix? also I've found a bug which is drag window to corner unable to make window half screen size.
I'd love to see groupy have more feature like tab color tag and keyboard shortcuts to quick switch over tabs
Please make sure you drag the windows clicking and drag on windows titlebar not on the groupy to ensure windows snap. i.e. make windows half screen when drag to left/right screen edge, or you can use "windows + left/right arrow"" key to achieve the same.
You can choose groupy tabs color via setting -> Visuals -> Colors click down Button.
Keyboard shortcut for quick switch tab is available. Configure at Setting->Configure hotkey...
