Pls add rename cards function

[Makein]

Based on names and sex pls add it

[im-mi]

Is there any particular reason you'd like to have this feature? You can already search by name and sex regardless of file name.

Besides that, it's currently a little outside the scope of the program (namely, a read-only card database). However, this may change in the future so I'll keep this issue open for reference.

And lastly, if you're handy with scripting it should be possible to export as TSV and use the resulting data to rename the files to your liking.
