Totally agree with this. One of our models has a processing time of 5-10 minutes which can be particularly frustrating at high usage times around month end.
In our team we try to make fun of this - who is going to freeze Anaplan for the longest time? :)
But to be serious, are there any plans to get rid of this 'feature'? We have 3-4 model builder working on a model at the same time and having to wait such a long time really stops everyone.
