Thanks! Not exactly what I was looking for, but that will do :)
Would be great to have some space for notes, separate from the connection name.
Sometimes I have two connections for the same server with separate purpose (usually just different user). So I add short notes like "collector (for artifacts)" or "collector (logs)". Using name for notes like that is not ideal because the tab of WinSCP becomes quite long, especially when duplicating session (and current folder is also added to the tab).
So I think it WinSCP could either have a short name (along with current, long name) and the short name would be visible only on tabs. Or maybe add some kind of notes that would be visible on the connection list.
