Option to group and label icons

[schrmh]

Is your feature request related to a problem? Please describe.
I have some apps open multiple times and for each instance they have a icon but I would also like to group similar apps (e.g. messaging).

Describe the solution you'd like

• Option to group icons together based on window name
• Option to freely group icons together based on user defined rules
• Left click to open group in either a separate window or in the same stalonetray window but with a back button displayed
• Label that displays when the user hovers over the group
• Custom icon for group (static image would be okay but some ideas for options: displaying multiple of the icons part of a group but smaller or displaying the last icon that got a indicator)
• Indicator for the group in case there is a indicator on a app in the group (not 100% sure how you could get that info but displaying it after a icon change might be good enough... or just give the users some scripting freedom here and they might figure something out by themselves)
• (Custom) context menu entries for the groups (e.g. launch app xyz from the group)

Describe alternatives you've considered
I heard about a GNOME extension that introduces groups for the system tray there but I never tried it since I don't use that DE...

Thanks for the feature request and awesome writeup!

On one hand, this request makes sense to me. If you have many icons then grouping them would have been useful and the described behavior is reasonable.

On the other hand, this project is mostly on life support. So, patches are welcome.
