Im not sure if this will get anywhere but there is a feature an firealpaca and krita where you can save your canvas size, is it possible to implement that because honestly im getting sick and tired of reverting one size and changing to another for a different project.

For now, you can make a bunch of template/starter documents and begin new documents by opening them and then Saving As your new document. This is less convenient than being able to select a size in the New dialogue, but it does have the benefit of letting you set up layers, guides, etc ahead of time.
that would be neat feature.
another option is to have a script with predefined sizes. JJHaggar already made it few years ago. It’s small and easy to modify:
