The Projects feature is not fully implemented

Hello.
First thing : after all these updates , my software is at least doing well on my computer . So i am quite happy with it and has used it a lot these days. But when it comes to select pictures for a project i find it is very easy to do inside PL but very difficult to use for let say share them with people or a website . In my case i just wanted to select good pictures in my folders from a trip and assign them by subject “landscape” “nature” … Very easy to do it with photolab but when i try to put them in google Photos Album all i can do is open a project ,select all then rename them all to mark them by subject and finally find them in windows explorer to find them from the google photos dialog. Not very smart as i have to rename them to the original name after .. Maybe i am a bit silly with the feature so i ask you i you have a better way to manage pictures withe the project feature.
Thank you for your answers.

Maybe it’s easier if you try something along these lines:

If an image is in several projects, all that is done individually in projects, accumulates in the original file’s settings and metadata. There is no “separation by project”. For “separation” (by metadata, filename, settings etc.), VCs are better suited, but if you need different names or metadata, they must be set anyways…unless you do the renaming in export.
