[Suggestions] [1] Add advanced mode and flags to the preferred (audio) languages and [2] remove the character limit from the subtitle selection string.

Hello, I have two suggestions and Im posting them hoping they will be taken in consideration.

[1] I wonder if it's possible to add the advanced mode to audio to activate the simple flags (|dfn) for audio too. In this way, it would be possible to select a language only if it's default, and, if it's not, select another one. Example: ita|d,jpn,ita,eng

[2] The character limit of 255 is, as the word itself says, limiting. It would be amazing if it was possible to make it (a lot) bigger.

Thank you for all your work.
