JK has released a new version of his Save manager for the 2ds/3ds:

07182018 :
Fixes a major memory leak I missed
Tweaks the menu item count up to 17 instead of 15
Reads and forces a cache update from previous versions. I'm sorry, but it's needed.
Removes the leftover, unneeded UTF32 titles from previous versions
Adds '.' to the forbidden char list fixing Smash folders

I wanted to hold off on a new release until the file browsing mode was done, but this is important. Sorry for any inconveniences.

07122018 :
No, I'm not dead yet. The newer rewrite is much closer feature wise to the original with a few improvements I've wanted to add over the past year.

Titles are now filtered according to whether or not JKSM can open anything for them, save or extra data. This eliminates the need for the filter.txt.
I've added a much needed "Jump To" button. This allows you to type a letter and jump to the first title in the list that starts with it.
The folder menu no longer locks the program into a loop and can be exited like the rest of the program
The backup and restore menus have been merged into one menu.
It no longer relies on 8 libraries and can be built with just citro3d and citro2d
Color scheme has been updated to match the Switch version

Shared Extdata has not been added yet and an advanced file browser mode is planned.
