So, one step by the time.
I have first registered on the Gitlab.com instance years ago, while never done anything substantial.
Now I have found an issue on the homepage of a project that I like and login in via Github.
Now the horror started.
First: You lose the changes in the edit fields when the page gets closed.
Github stores that locally, so it survives even a reboot.
Second: Since the git tool considers pull requests a host-specific thing, there is no support for it in it implemented. Therefore, tons of third-party tools are there, who supposedly help to commit.
The mentioned change happened in dozens of files, I dont want to edit that in the web UI.
Funny enough, those tools require extensive configuration and/or dont work at all.
I recommend strongly to take up your attempt from 2014 and produce an official tool.
One that is preconfigred and nicely documented. Especially how to make pull requests.
Great.
Third: Your documentation is partly outdated. With old screenshots. On such rarely used features such as forking. https://docs.gitlab.com/ee/gitlab-basics/fork-project.html
And of course duplicated: https://docs.gitlab.com/ee/workflow/forking_workflow.html
If that is the quality on the surface, I am afraid to even glimpse into the source code.
Forth: Clicking on the nice button on the bottom of the documentation, in order to raise an issue, I get redirected onto the sign in page, while I am already signed in. I guess this is something security related.
So, I click on Github login again and it tells me that the login has failed since the Email is already taken.
And funnily enough, the screen offers me to login via username/password, despite the fact I was just trying to login via Github. I guess there are for sure people who actually make a Gitlab account who is then connected to Github, for which reason ever, while the majority of the people are simply confused.
Conclusio: The goal, to edit a couple of text documents ended in my impression, that this project has still a lot of harsh edges. Thanks a lot for reading this.
