Daily. usually noteapd++, recently moved to Atom as it includes Less for css, which is quite helpful.
Using editors (WYSIWYG) only leads to bad HTML/injected trash into code. (LESS does this too, but to an extent that it is acceptable because of minification).
It’s not as bad as FrontPage mind you. But it’s still just bad.
Then again, I even do SVG on notepad because otherwise trash is injected and bloated into it. So I’m definitely not your average design whom you should probably ask.
UE4 BP is much like frontpage was to HTML.
It makes a mess and slows performance down.
It’s acceptable, because it’s QUICK and Visual.
But if you are trying to do things right it isn’t the correct tool to use. Just like you wouldn’t use a celeron to compute Pi digits in 2021.
I agree wholeheartedly that the whole animation system needs a revamp to be more modern. (And better docs as I asked already).
Even with those changes, I’m not sure it would matter much for usability until they resolve whatever the internal issue with rendering is.
