I have a big set of sgf files (Tsumego Collection) with various sub-folders.
I tried a few different sgf viewers on my android phone but none of them are very convenient for keeping track of progress through the list. I want an app which remembers which files I have done/opened and what my next is. Preverably per sub-folder.
Does such an app exist?
(If it doesn’t, maybe I need to develop it myself, shouldn’t be to hard… Only the keeping track of which are opened, the viewing itself can be done by another app)
