The biggest things that cause friction in SublimeText compared to jEdit are the tabbed views instead of separation between Buffers/Views.

Then there's hypersearch, which is still the most versatile search implementation in an editor IMHO. (Perhaps a ripgrep integration underneath would speed it up!)

And there are the Highlight and SFTP plugins which are amazing and surprisingly hard to find (not that there aren't any, just not with the same specific nuances).

I could wax poetic all day. Thanks for jEdit.
