@Lea_WMDE can you have a look? this would be done from my side.

@Charlie_WMDE having the preset inside the search box means us having to override OOUI things, which means we would not be able to use their updates. And we would have to do quite a bit of calculation ourselves to position this correctly. Also, storytime resulted in some doubts whether the positioning makes sense, especially when people opened the dropdown before. Could you imagine a way that this is not inside the "Search in" dropdown box?

@Lea_WMDE Yes I can imagine some other options but they all have UX flaws that I was trying to avoid. This was the best solution I came up with from a strictly UX point of view. I think it would be best if we can have a meeting to discuss the technical constraints so I can better assess what a feasible solution would be.

Change 417945 merged by jenkins-bot:
[mediawiki/extensions/AdvancedSearch@master] Add checkbox for "Remember selection for future searches"

https://gerrit.wikimedia.org/r/417945

This is not working for me: It looks to me like the previous default settings are merged with whatever I have in the input box when I search (and then search again) after having checked "remember selection for future searches". I expected to only be searching in the namespaces that were selected when I checked the button.

Furthermore, the positioning looks a bit weird, maybe this has todo with the OOUI update, that we previously had buffers around the checkboxes when they still were smaller, and now these buffers need to be removed?

@Lea_WMDE now that the feature behaves correctly and we're only left with the weird looking checkboxes, I talked to Hanna and the fastest solution we have is to increase the space between the checkbox and the label, because it makes it more clear which label belongs to which checkbox. Still not perfect and still weird looking, but further improvements will be for another task.
@Charlie_WMDE takeover :)

@Charlie_WMDE
the problem: After adding "Remember selection for future searches" it was established that the namespace presets look strange now because the checkboxes are bigger than before (as a result of an OOUI update). You can see that on uca test server.
the quick solution: Increasing the space between the checkboxes and their labels seems to make things a little bit better.
other discussed solutions:

• Override the checkboxes to make them small again.
• Increase the space between "Search In" and the first row of checkboxes.
• Generally increase the dimensions of the component that holds the namespace presets.

@Hanna_Petruschat_WMDE please correct me if I'm wrong or missed something from our discussion.
