I absolutely LOVE Keepboard! Its keyboard driven interface makes it quick and easy to use. I use it to not only manage my clips, but with Favorites, I use it as a bookmark manager as well! It would be great if it had a dark mode. I run ALL my apps in dark mode so it is blindingly bright in comparison. Thanks!
BTW: I was having issues with the globalization features, so most of the labels etc are hardcoded in my source code. That may be due to my lack of knowledge - or that I'm not using an IDE (Just using VIM).
If anyone is interested - I grabbed a copy of the Jreepad source code and have made a 'murdered out' version (All black w/ white txt). I'm updating it to my own personal liking - so I added a horizontal rule function (with optional heading) and added a super basic search within current article feature and tab size preference. My code is on Bitbucket if anyone is interested: https://bitbucket.org/baiguai/jtreemurdered/src/dev/
