I did not yet test-drive this (also because I ran into #1653 while I started working on this).

I leave the discussion whether such a feature is desired to the issue (#1654 ) :+1:

[matthiasbeyer]

Also, this feature somewhat contradicts the filter_mode setting I guess, because implicitly the first entry in the filter_modes_list is the default, right? :thinking: We might want to have some discussion about this as well.

Any ideas about this?

I think it would make sense to add a [search] block

So

[search]
filters = ["session", "directory", "global"]

When set, it will override filter_mode and any other related settings.

Wrt workspaces, I'd suggest the following

1. If a filter list is set, does not contain workspace, and workspaces = true. We should work with the current behaviour, of switching to workspace mode.
2. If a filter list is set, and does contain workspace, then follow the order set in the list - regardless of whether workspaces = true.

I'd love to see this feature!
