2.0 is live! Everything seems to be working, but there will probably be a few bugs here and there. If you find any, let us know!
We will be able to support import from Chrome and Safari when 2.0 launches, in addition to the already planned support for Firefox and Xmarks. At this point we can more or less handle just about any kind of export file you can throw at us.
By the way, Apple has deprecated developer-signed Safari extensions in MacOS Mojave, so before Fall I'll have to build a new Safari extension. I am annoyed at the extra work, but this move is designed to keep (other!) extensions from tracking you, so it's hard to complain.
I am (finally!) almost done with the categorization features, and the Xmarks / Firefox importer along with them. I had hoped this update would be ready quite a while ago, but we're getting there. I expect to roll out the update within the next week. For real this time!
Sorry about the delay on support for categories, and for the Xmarks / Firefox importer. This project has turned out to be a lot more involved than I had anticipated. Mozilla's ancient and weird export format is very difficult to work with. Stay tuned.
