Thank you so much for your feedback.
Let me make some observations:
The "package manager" (https://tilepieces.net/documentation/panels/package-manager....) is not only used for projects, but also to create / load / export components (https://tilepieces.net/documentation/data-structures/compone...), and to set the global properties of the application. So I think "Package Manager" is more appropriate than "Projects view".
As for the windows (I think you talk about panels -> https://tilepieces.net/documentation/UI/panels.html) they can be set right, left, above, below (they are fixed below 1024px). They are certainly a bit .. rough/raw/sketched i think you could say... as everything to the UI, but at the moment I think the important thing is that they work.
The third point you are referring to is a bug! I swear it worked until yesterday :)!
