So, I've been working on Tarmac for about 2 years now. In those two years, I've figured out that Launchpad still doesn't have a good model for replacing PQM just yet. We do our best to use the existing model, but there are still some oddities.
...until now...
Now I'm working on making it easier to queue up merges, and either have a merge controller person perform the merges OR have Tarmac do it for you (the best option). I cannot begin to tell you how excited I am to be working on it.
