Added some stuff to Design history animation but I'm not comfy with GitHub workflow

Hello there,

First of all, thank you for this repo. It's really usefull.
I downloaded the code and added a fiew things like managing sketches display, managing two sides angle revolve features and implementing a camera rotation proposed by Fusion 360 here https://help.autodesk.com/view/fusion360/ENU/?guid=GUID-AC5A8134-2634-4077-9BD5-16B2945CBFDD.
I plan on adding more stuff.
However I'm not used to GitHub, I pulled and pushed things only a few times in my life.
What's the best way to add the stuff I already coded ?
And what's the best way to implementstuff in the futur ?
