Support fuzzy search in the load/move custom groups popup
Is your feature request related to a problem? Please describe. I use the extension heavily, and end up with a very long list of tab groups. In the load/move custom groups popup I miss a better way to choose the target group rather than having to scroll through and find the exact group I want solely by position.
Describe the solution you'd like Support search on the load/move groups in-page popup directly, doesn't have to be the full per-tab title search of the sidebar and toolbar popup, a simple fuzzy search on the tab group names would work perfectly.
Describe alternatives you've considered Load/manage groups using the sidebar or toolbar popup, but both seem slower on hotkey-press, and I enjoy the larger UI elements of the in-page popup.
Additional context
Looking through the implementation, this piece of UI seems to be managed using the DOM API directly in showGroupsPopup(), in addon/src/web/content-script.js. Most of the existing search code exists in Vue components, so it may not be so straightforward to port here. I'd be happy to help contribute with a PR for this feature, but I would need a bit of guidance.
It would be awesome, +1
