Import doesn't work Rated 3 out of 5 stars
I created one bookmark in Keepbag, then exported it.
Then I deleted this bookmark and tried to import the exported file.
0 bookmarks were added.
If this addon uses some specific format, it should be converter that can transform html/json files into this format...
Without export/import this addon will be useless - currently it is impossible to recovery data.
