Architect 3.1 and Ext JS 5.1.0

So, I guess Ext JS 5.1.0 is for people who don't use Sencha Architect? It keeps saying "Restoring SDK" on the "Output" tab's title at the bottom at regular intervals and it's otherwise very slow to use now.

Will there be an update soon? If Sencha Architect isn't supposed to be just a simple GUI code generator like it was back in the Ext Designer days, then why aren't SA releases timed to coincide with Ext JS? Unless SA is going to show big warning messages to developers who try to use versions of Ext JS it doesn't yet know about, then you're only creating a situation where developers' time is wasted and your reputation takes a hit (more than the huge price increases have already done, that is).

I think it would be wiser for me to just go back to 5.0.1 and wait until after Christmas than to keep banging my head against the wall with 5.1.0 in SA. I thought the price rises would chase me away but it's these constant upgrade nightmares that will probably do the trick first.
