Ahh, all of that is good to know! I haven't even attempted to dabble in anything overly-complicated on Wordpress. The most I have done includes adding a couple of widgets and cheering at myself because the most basic things worked. 😅
I'll need to get a handle on the commerce aspects this time around too, which is terrifying...
I'll have to keep SquareSpace in mind if things get a bit too... headachey. 😬
