i think the GUI of the seafile client could use a redesign. having all libraries in one long column is starting to get very uncomfortable with many groups and even more libraries.
i’d suggest to add a sidebar to the left, similar to the seahub web UI, where you can toggle the view on the right between your libraries, groups and the subgroups that are currently below each other (my libraries, shared with me etc.).
while you’re at it, you could then add a few more helpful fiters like “paused libraries”, “files shared with me” or “libraries with issues”.
