Does joplin repo has any progress tracker or development dashboard?

I am contributing to joplin , but whenever I solved an issue or want to discuss the solution in the comment of the issue , someone has already made a PR for the issue even I am the first one on the issue to comment that I am working on this .
Maybe it's because someone is working even before I have commented on it .

So is there anyway how to know that someone is working on an issue . Is there any progress tracker something ? or do I have to first comment & wait on an issue to get that assigned to me it and then make a PR for it ? I am asking this question because I have faced this problem 1-2 times & I don't want my time get wasted on an issue on which someone is already working .

I am sorry to make a topic for this type of doubt because I don't find anything related to claiming an issue in the CONTRIBUTING.md file

There's not enough people working on the project for this to be needed. If it happened it's quite exceptional and I think the issue you mentioned involved about two lines of changes, so it's hopefully not too bad. I don't expect such confusion would happen for large issues (at least it never did).

Ok.. but I didn't get any update on my last comment regarding the issue so I halted for a moment because I don't want to tag someone & ask for update because everyone is busy in their own way otherwise I was ready to make a PR for it.

So to work on an issue I should first ask someone to assign it to me ?

We don't assign issues either.

ok so I have to directly make a valid PR for it
