Changelog:

Major GUI update.
The used theme is now selected via the current system theme.
Files/directories starting with name '.' are now ignored.
Args are now handled properly.
If {dirname}/{dirname}.nro is not found, the NRO found via dir-listing will be used instead, if there's only 1 NRO in the directory. This only applies for paths located under "sdmc:/switch/".
