Optional Cache?

[jabhq]

I have 27k bookmarks!
'B-C-M' I assume reads them all at startup (Ff hogs cpu for a couple of minutes).
Would it be possible to provide a cache option to avoid re-scans (with a Refresh/Update button for new BMklets) ?
Or ... a way of accessing just BMklets ?

Actually there is not way to get only bookmarklets with the WebExtension API (you need to parse the whole bookmarks tree).
But it's possible to implement such feature (manual refresh only) or use WebExtension bookmarks API with more granularity
