Like what I need most from IDE UIs, I like the fast code coloring, error pointing, multi-file (and regular expression) search / replace, and edit access to code-linked files / assets.
It's UI is bloated with very edge-case actions / options. High level most-common User flows are not streamlined. This makes it very difficult for anyone new to the program, and especially anyone new to HTML / CSS / JS coding. As an IDE it's not as complete or useful as Eclipse for instance. So I'm not sure who the target user audience is here?
Search / Replace is not as good as past, tiny window, requires multiple clicks to do what was easy before but, at least it isn't completely broken like last year's build.
CSS suggest in current is clumsier than past, requires mouse move to confirm tag, then mouse move to click possible value (or just type it and be bothered by huge intrusive DW windows); I suggest adobe sees how chrome dev tools does it, suggest in place, user tabs to move to value with most common value suggested, tab, save.
Preview in browser is a step backward, loads overhead adobe code to 'produce' a view, and sometimes it isn't able to load. I would prefer old way, best way, just launch the saved file in a window as if I clicked the file or opened it from that browser - to update, I can just refresh, that's fine with me.
2018 version was lame, as mentioned, Find & Replace was completely broken, also the app crashed often, data disappeared, arghh. Had to roll it back to 2016 version which still worked okay.
Support contact with Adobe was bad - huffy replies that maybe I'm not using it right.
Good news, 2019 version seems stable, just not as clean a UI as in the past, and not focused on most common work flows.
I'm able to make basic HTML / CSS / JS content pretty quickly.
