This can also be set via GUI (System settings) in KDE desktop, to always open and keep Thunderbird on a specific virtual desktop (workspace), maximized. Then there is a setting to not show apps from other desktops in the taskbar. But TB icon will be present in the systray on all desktops.
On Windows this may be useful (and Outlook supports it at least up to version 2013), I'm not sure how the new "virtual desktops" in Windows 10 work. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/376715 Title: Thunderbird - feature request - nest in toolbar To manage notifications about this bug go to: https://bugs.launchpad.net/thunderbird/+bug/376715/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
