I am also wondering the same thing as OP. Somewhat tangential thought, but I recently realised that what I would really love in an IDE is a "first class" Markdown editing experience, just because most of my day-to-day is managing and writing docs rather than editing code. Cursor has Markdown rendering support of course but it seems to have two implementations, each sort of clunky in their own way. And I want something more WYSIWYG but with Latex / flowchart / etc. support built-in. OpenKnowledge seems to maybe fill that niche somewhat (it also supports annotating Markdown with comments to feed into an agent), and has agent integration within the GUI, but one killer feature that seems to be missing is Remote SSH support (short of hosting its web server on the remote and having the IDE live in the browser).
