It would be absolutely great if you could upgrade it so it will be able to also bundle templates with their possible dependencies, which can be hard bread to bite! ¹ That is something I already asked @Srirupa_Datta for, back then when she was developing the new Bundle Creator that we will get with 5.3. ² But I have to admit, this won’t be easy!
And then I would like to be able to bundle all the resources we currently can’t add to bundles, so all those resource types the original Krita bundle editor lets out, but that do not depend on dependencies to fulfill. That means you simply have to add them to the BUNDLE (ZIP file) to create and to unzip them in their respective folders when importing a bundle into Krita, which should be easy to add.
Here, for me, would be especially important layer styles, which, other than you would expect, are saved as ASL files in the folder asl in Adobe Layer Style format, but also color-schemes, input-schemes, predefined image sizes, preset icons, shortcuts and symbols would be greatly appreciated, although they are mainly niche resources most users will never touch.

¹ In the subfolder tetimpressio\layers\ of the respective KRA file for each template, you must scan all *.filterconfig files, of the individual templates, for file references to patterns that may be used in the template so that they can then be added to the BUNDLE (I think I explained this in Pesi’s watercolor brushes thread, as he had an error in his template that referred to a local resource that only existed on his computer and made it hard to use his “watercolor page” he offered in his “template construction kit” for that “watercolor page”. Therefore, I offer there a fixed version of that “watercolor page” template).
² The topics were: Bundle Creator: Improving the UI/UX design and Bundle Editor (New Feature), but she let it out, probably because it is not easy, or was not easy back then, maybe AI may help writing a routine scanning for the dependencies.
