I've been hesitant to pull the chord on a paid HTML editor, but I'd used a free version of Coffee Cup in the past and was happy with it. I'm still playing around with the trial version and getting used to typing in the code box again instead of the WYSIWYG window as I'd done on Kompozer and BlueGriffon, both of which were clunky at best.
So far, I'm enjoying it, looking forward to using templates again. The only issue so far is my site is very image intensive (car site) so when I open up my image gallery, it gets a little choppy.
I currently have a trial version on two devices. Would I need to purchase it twice?

No, you are allowed to install it on two devices.

Yes, I just discovered that. Thank you!
