I have reverted to 5.5 after finding issues with 5.6, some already reported. The biggest offender seems that when you quit Pinegrow it saves your session whether you want to or not. I was experimenting on a site, added some pages for test purposes and decided I would not go ahead. I hit quit and instead of stating there were changes did I wish to save them or quit without, it just quit and saved. Lucky I run TimeMachine. I also found Bootstrap blocks hanging with a loading indicator rotating forever. I also added a new Bootstrap page but had no access to any components.
HI @atilla, PG 5.7 is out now, try that out and maybe it will be better for you.
if not, well spotted on noticing that
