Could be yes - although I seem to think with my transfer from one Samsung to another it brought the files and settings over. Can’t remember for sure now as was over a year ago, but I did not recall any major issue.

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.

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.

Although it says it “imports Markdown” so not sure if it is an actual Markdown format editor.

I switch between Main, Recording, and Gaming. Apart from backgrounds I have some apps specifically visible in that Activity, and also have a filtered desktop folder for each (each Activity has files that are only relevant to that activity). I did a video about my switching at https://www.youtube.com/watch?v=wq-7KEeH7_U and how it differs from virtual desktops.

Then again, I always wish that many religious people would not stand up so vocally and be counted so much ;-)

Well I use Element for Matrix as well… but why not 10? You only really manage them once when set-up. After that, you just respond to whoever messages you, or you compose a message of whichever one. They no longer chew battery or data in the background. I have 11 installed and there is really no “extra” effort.
