Open last libraries on startup should be in libraries tab and not in appearance tab

[calixtus]

Imho not, because you do not configure a library option, but the behaviour of the GUI.

Difficult UX discussion. I lean towards the libraries tab, because this is more empty than the other.

[calixtus]

If I would look for an option about the startup of the GUI and how the GUI should look, I would not look at first in the libraries tab. The contents of a preference tab configure the inner behaviour of the feature. To show the last opened library on startup has nothing to do with how libraries should behave.

[Siedlerchr]

But semantically it is related to the library. Logical grouping of functions.
Appearence has the clear denotion of changing styles, e.g theme fonts etc

[Siedlerchr]

We deffo schould ask our users!

[koppor]

Two scenarios (two times two tabs side by side; picture) then let vote? 😅

[calixtus]

Proposed change with this PR:

Mockup with the "open last files on startup" in the libraries tab.

We probably should then also include the setting to open the last opened shared databases here too (#9843)

JabRefFrame and JabRefGUI will have to be changed to use the LibraryPreferences.

Imho, this is nonsense.

A quick survey on different applications:

How IntelliJ handles it:

VSCode sorts a compareable option in "Workbench"

Firefox in General:

MSOffice / Notepad++ / Gimp / does not provide that feature (at least i did not find it)

@Siedlerchr can you please check, how eclipse handles this and post a screenshot?
