Looks quite good, I will give it a try. Thanks!
I can recommend Logseq
Joplin has this functionality, although I don’t often use it since I prefer to type directly into the Markdown editor. Whatever you choose, be sure that you’re comfortable with the security and privacy implications of it.
Silverbullet is like that. It is not an electron or native app, you have to run a server and then get to it from the browser.
TLDR it is best run with docker or podman, but IMHO it is pretty good.
I'm not entirely sure if this is what you are asking, but it looks like it is: https://github.com/Zettlr/Zettlr
Looks good and seems to have tab splitting, which marktext laggs. I will check it out, when I have some time. Thanks!
I use zettlr -- it's pretty good! The only issues I've run into are with the table editor, and with occasional lag on large documents; the latter just comes with the territory on an Electron app. I know Nathan's working on both, though.
Marktext does this for me, can't compare 100% to Obsidian as I've rage uninstalled that several times within an hour of installing it.
Zettlr does this reasonably well. It doesn't do it by default, though, you have to turn it on in the settings
QOwnNotes (https://github.com/pbek/QOwnNotes) may be an option as it is pure Markdown and need not have both the code and preview windows open. I used it before moving to Obsidian. It has some options to customise its window views, but it is a long time since I used it, so not sure if it has that block mode you want. Logseq I seem to recall worked with blocks as it is an Outliner that does save in Markdown format, but I did not like that the outline blocks added characters to the file format that slightly broke compatibility with standard Markdown formats. But blocks was Logseq's strength.
Make one, share it here. Would love to use it
~~I can reccommend Trilium. I think it has what you're looking for.~~ | Nevermind. Looks like the project is in maintenance mode for now.
https://github.com/TriliumNext/Notes is a fork that appears to be actively developed. Found it near the end of the issue linked from the maintenance notice.
Although it says it "imports Markdown" so not sure if it is an actual Markdown format editor.
Trilium supports writing notes in multiple formats, including Markdown.
I was thinking more of its native file format it saves to. It said "import from Markdown" which seemed to suggest it is not saving all in Markdown (otherwise would have said opens and saves to). But maybe it is just badly worded.
Ah, you’re right - Trilium doesn’t use file-backed notes at all - it saves them in a database (I think Sqlite but I’m not positive).
