I looked for various front ends for Dosbox but could not find one suitable for me.

So far I have used Ykhwong's DOSBox only because it has (improvable) game snapshot management and allows (always improvable) to manage game recordings and other convenient controls in a beautiful top menu.

I am looking for, if it already exists, if not I ask if it is possible to create it, a program similar to Ykhwong's DOSBox but in addition:

[*] I would like to be able to name the saved state. Without limiting the number of them.
[*] I would like each game to be associated with its state saves: for example, the saves will be stored in a subfolder of the game's folder and loaded in the "Load State" menu when you start the game.
[*] Some games as handle multiple users. Others handle only one user. For games that do not natively support multiple users, I would like the ability to manage multiple users, and each user has its own saves and snapshots. I am well know that DOS games are generally small and multiple copies can be created without consuming too much space, but it becomes chaotic to manage.
[*] The ability to save game videos even in modern vodeo formats (like x265) lossless.

Keeping the program portable.

I play mainly on Windows, but I would also like an Android version.
