Hello @Greifi ,
we are going to change the label “Coming soon” into “Vote”, because it leads to a wrong expectation. The goal is rather to find out our users’ interest in certain apps. Besides GitLab more apps will come in this category in the next couple weeks.
Concerning GitLab, there is currently no activity known to me to bring it into the App Center. With other apps you can vote for it gives us a better picture about where we should prioritize our activities.
