Markor is a lovely text editor, shows off what the best of FOSS can be like. It's slightly fancier than a more basic notes app, but loads just as fast, and has enough configuration you can make it what you want it to be.
I've had problems trying to store notes on the SD card, but I'm not sure if that's a Markor issue or an issue with the sync app whose folder I was trying to save into (and it's more fundamentally a problem with Android's dumb handling of SD card permissions anyway).
The dev is active and responsive on GitHub too, which gives me good hopes for the future of the app as well.
