In 2023, the current search dropdown is :

* favorites

* tags

* highlights

* type -- articles, docs etc

* operators -- creation date, inurl etc

* untagged

Sidebar shows:

* Collections

* Filters -- incl favorites

* Tags

Perhaps an option to reorder these three upper groups would be preferrable. Or maybe like filters/tags, one collapsible dropdown to nest all collections under, for quicker navigation between groups.

Ideally it would be great to let the user organize the order of the left menu items

Totally agree. Don't know why he made the decision to put it at the bottom.

Favorites -> 1st things 1st

Collections -> normal browsing

Filters -> special tasks
