2D Animation software

Greetings and Happy New Year everyone!

I'd like to please request some 2d animation apps that I use often and are very good. All these are Open Source.

1st one is Opentoonz: https://opentoonz.github.io/e/

2nd is Synfig Studio: https://www.synfig.org/

3rd is Tahoma2D (Opentoonz fork): https://tahoma2d.org/
(I don't know if this one has a portable version already since I don't use it that often)

Hope to see these or at least some of these apps implemented in the future as they would be of huge help to people like me who don't have much computer space, or need to store apps in a usb drive ^^

Thanks!
Best Regards!
