Hi, I just imported some 6,000 Evernote web clips into Bear. There were grouped into a large number of tags. currently a simple way of handling the resulting long tag list is to rename each tag to something like evernote/tagname. this will put all the clipped tags into evernote and greatly simplify the tag list in teh left hand panel.
After that you can add your other notes and tags in any way you like.
