I would assume its basically the same as gitlab, except with any 
proprietary removed and that new features land in the enterprise version 
first and presumably migrate to the FOSS version over time.


What works well?  If you've wired up some CI bits, it's is extremely 
useful to test an under development patch.  Develop, push a branch, 
raise an MR.  At that point the CI system kicks in.  Subsequent pushes 
to the branch trigger fresh CI runs.  This aspect I really like and if 
you were to see internal flows, you'd see dev branches churning as a 
patch gets iterated on.  It also has features like "when this passes CI, 
automatically commit it", which we often use on the final patch 
iteration if there was a nit of some kind.




What doesn't?   Finding things in gitlab is *awful*.  Now we're just 
talking about one repo, so it may be more manageable in that regard. 
And we're not talking about using it for bug tracking.  As long as we 
kept on top of the MR queue, maybe it would be feasible.

So maybe I should soften my stance on gitlab.  If we're not using it for 
bug tracking and hosting many projects, then maybe its viable.

I think the driving force will be whether or not folks like you, Richi 
and others that do a ton of patch review would be more efficient in a 
gui or not.  I don't think I am, but maybe that would change if I did it 
every day for decades like I did with email :-)
