This looks like something usefull. Some observations after first start…

• why does the app requests full file rights, after I selected my local notes folder? If the app has access to that folder (and subfolders), this should be enough.
• for code, examples a code font should be used and not the same font as article text
• i use markdown a lot for code. With this it should be possible to select the whole code block by single click. When using css, this should be possible with > user-select:all
• auto line break should be disabled in the same context. This seems to be already the case for code block but not for single line code
• i would love to see support for yaml. But in the form that i can hide the yaml block
• i think the search feature doesn’t work yet. If I have for example a note with the title Manjaro.md and I type “manjaro”, it isn’t found. The search should also search the text inside the notes or at least the yaml tags (if supported)
• please keep the local folder and don’t invest your resources in a sync mechanism. There are so much possibilities like WebDAV, rsync, SFTP and a lot of clouds. To much to make anyone happy. There are some Android apps which sync such things with an ease.
• I keep my rare images in a hidden subfolder of the notes folder like “.media”. Not only images, also linked PDF and so on. Such images are not displayed. They seems to be not found

I really like the idea of your app. Could be a good companion for my PrimitiveNotes plug-in for Roundcube. Hopefully you find the time to develop it further.

Unfortunately, this version violates the DSGVO by sending telemetry without being asked. This shoots the app directly into out. I hope that the developers have an insight here and remove this function as soon as possible.
