I found out that GitKraken has support for profiles "Multiple profiles for work & personal".

I use Groups, but normally I work with big projects with several repositories. I use groups to 'join' the repositories of my Products/Projects/Modules/Libraries. I have several groups ordered by alphabetic order (mixing personal, company work and multiple-projects).

Having groups inside groups would sort of fix the problem. But even if you work on several projects would be easier to have only the 'working set' of the repositories and groups that you really need.
