Description

Received some strong feedback about the new grid selector modal on discord
- Most users are finding the headers per-source to be too much clutter
- They don't find it intuitive that clicking the "facet by sources" button switches it back to the old style
This PR:
- Reverts the default view back to grouping all cards together
- Sets the menu for jumping to a specific version to be collapsed by default
- Labels the button toggling between grouping all cards together (like the old system) and having headers for each creator, and its text should more clearly communicate what it does
Left for another night:
- Making the export project -> download desktop tool workflow clearer
- Looking into speeding up image downloads further
