Encryption option to change keysize

Greetings

I’ve recently started to use Joplin and find it very useful, especially the end to end encryption.
But from what I’ve seen it seems that the notes are only encrypted with 128bit AES. I know it is faster than using 256 bit keys, but it would be nice to have the option to change between the different keysizes in the
Encryptionoptions menu.
