I'd like to help you out but I don't know what door your came in.
who understand ps? they will burn down the house to get best framework, anyone that compares for instance ps performance config to 'any' other ecommerce would see clearly that 1.7 one ccc of .js/.css is state of the art, nobody has or will catch up with ps on this.
1.7 is 'far' superior to previous major releases but yea there is no reason to jump if your business is booming and you have all the features you want, but guess what? With 1.7 template inheritance we can now 'finally' write feature rich modules that could not be created for 'all' previous versions, must like is done on shopiy 'liquid'....
I could go on and on but wait for my podcasts so I don't have to spin up shop managers/developers/etc. one at a time jajajaja
getting bad? when one is over the head, running standalone ecommerce is not for weak or unexperienced, while easier to blame the platform maybe it's you.
happy selling, el
