Automatically register new workspace folders for source dependencies

Please compare the UI experience in Metals vs Intellij; I have uploaded screenshots of the sample project imported into both. You can see that Intellij presents the second project as a full peer of the top-level project, whereas the Metals experience confuses me and I cant do anything useful relating to the relative p2 project.

Import Experience in Intellij:

Users can already manually attach workspace folders via https://code.visualstudio.com/docs/editor/multi-root-workspaces

This is a feature request to make Metals automatically register workspace folders. There's no endpoint in LSP for servers to register new workspace folders, only to read existing ones https://microsoft.github.io/language-server-protocol/specification#workspace_workspaceFolders We could add a new client command for it like here https://scalameta.org/metals/docs/editors/new-editor.html#metals-client-commands

Just want to check in on this one - not meaning as a simple "bump", but I'm not sure this issue is something way bigger than what I need.

My need is not any automatic detection of source dependencies, but just being able to have more than one Scala project in a vscode workspace. Is it easily possible to register multiple ones at bootup of metals already? That would be good enough for me, but currently I need to open multiple vscode instances just to be able to work with multiple Scala projects using metals which is a big annoyance for my workflow.

I couldn't find any issue asking for just that but I might have bad search foo today…

I think there was a discussion on this on some other forum and I never really understood if this particular issues is aligned with what I'm asking for. So question is if I should open another feature request for my possibly "simpler" need…?

I found #1758 but my understanding is that this is for selecting between different build tools in one workspace folder…?

@hedefalk I think you are looking for scalameta/metals#5188 - this is something that we still miss in Metals and would be awesome to implement, but we haven't had the time yet.

Thanks, my search foo really was bad today :)
