Zettelkasten and the virtual directories
All in all, I'm a big fan of the Zettlekasten. However, I think that Zettlr is not yet perfect for this function. First of all I miss the function to scroll through my notes with the arrow keys. Second: the "desk" function of zkn3 is missing.
It is incredibly handy for writing long papers. Several notes are arranged under headings and output as continuous text. The virtual directories were near that. I hoped that these will have similar functions sometime.
Therfore I think it's a bad idea that this function will not be continued.
