I have just bought and installed InSync as part of my migration away from Dropbox to OneDrive.
I am using Fedora 31 with KDE Plasma. The icon appears in the tray which is excellent and I also like the fact you support a proper RPM repository so I can set it up with Ansible scripts.
Onto the feedback in order of priority:
Clicking on the tray icon makes the program appear but clicking on it again does not minimise it. This isn’t following the same workflow as other tray based programs (both KDE native e.g. Konversation and non-native such as KeePassXC). Would it be possible to add this as an enhancement?
Minor - it would be nice to allow the ‘Help/Release Notes’ with the version to be copied and pasted as a convenience. Its not a blocker as I can do
rpm -q insyncgiving
And finally a question - does the program provide a tray status of ‘syncing ; x amount still to do’ ?
