Add Collapse all filters option and preserve open/close state

What problem do you see this solving
Some filters like date and keyworks are always open each time the app is started.
With a long list of nested keywords and dates it is awkward to use filters.

A "collapse all" button and preserving the open/close state of the filters on quit will be very helpful.

When was the last time you were affected by this lack of functionality, or specific tool?
This affect the whole experience of browsing pictures using filters.

Are you using any workarounds or other solutions to achieve your goals in Capture One?
I'm displaying only the keywords filters and with few root keywords to keep it easy to manually collapse them on each start.
Showing only the keywords filters also improves a lot the performances of navigation

Are you happy to be contacted further about this suggestion or request?
