My main requirement is that I am using Syncthing to sync my notes from my Android phone, which uses Quillpad. Quillpad is amazing and looks super nice, and functional too, but all the notes are in one big folder rather than being subdivided by notebook. So I require a markdown editor that can create “notebooks” but don’t change the folder structure of the notes (I tested putting notes in subfolders, and quillpad thought the notes were deleted. Silly Quillpad!)
So the notebooks/similar organisation of notes needs to be specific to the app and should not change the folder structure. I would prefer if the app is open-source too, and something that fits with my desktop (KDE Plasma) would be cool too :D
This rules out Obsidian (which puts notes in a folder structure. Obsidian is great, but won’t sync well with Quillpad), Joplin won’t work either. Ghostwriter is pretty much a markdown notepad (quite good, but can’t see all my notes in one place)
I am using EndeavourOS with KDE Plasma
edit: To clarify, I want a markdown editor that is able to separate notes into different groups without using folders as Quillpad doesn’t like folders. I also need to have a way to view all the notes at once in each group
Using a code editor VSCodium wouldn’t really work as there isn’t really a way to organise notes, aside from putting them in folders (which I don’t want), and I am not yet ready to jump into the Vim rabbit hole of plugins and configuration
edit 2: Markdown editor to note organiser to satisfy the pedant
edit 3: Looks like Obsidian has tags, so I could use those to organise notes without folders. I will try that and see if it works!
edit 4: Obsidian does have tags, but it seems like you sort by tags by typing tag:#NAME, and you can’t use spaces for tags. So not Obsidian then unfortunately. Are there any other options that have a larger focus on tags or similar?


Yet more suggestions which you didn’t ask for:
GitNote might be up your alley. Its UI is not as slick as QuillPad, nor does it have as many features, but it does faithfully keep the folder structure.
Somewhat of a deal-breaker for me personally: It can’t do reminders.
Embrace the chaos. 😅 I have a little program for managing my notes on desktop and it just dumps them all in one folder, too. If I need to find something again, I’ve got a little text search, which is basically the equivalent of
grep -iR. I just make sure to mention enough keywords in each note, so that I can find it again.Personally, I much prefer this workflow, because you can start typing (and hitting Ctrl+S) and then later ensure that it has all the right metadata, rather than having to select a folder upfront where it will be saved.
I actually tried QuillPad not too long ago and couldn’t make it work for me, but being able to save as normal files seems to be a recent addition, so maybe that’s what I was missing.
I’ll probably try setting it up to work with my desktop note system then…
