@derei Regarding Issue No. 3, if you're on Win11, you can do the following:
Save the profile shortcut to your desktop.
Right-click on the shortcut on your desktop.
In the right-click menu, click on "Show more options" at the bottom.
In the expanded menu, likely in the middle, there will be an option called "Pin to taskbar". Click on it, and the profile shortcut will be pinned to the taskbar, with your profile picture thumbnail icon on it.
Repeat those steps for all profiles.
