Would anyone know of a better tool for designing the Advanced PDF/HTML templates? While I've managed fine using the on-site native editor, the time it takes to add elements and search for tags is terrible, and is highly-impractical in the long run. I haven't yet tried any tool outside of Notepad++ so any suggestions are welcome. Thanks.

I've always resorted to designing them in the source code view because yes, the wysiwyg editor is no good at all. The good thing about the code view is that you can get into some fancy logic that any wysiwyg editor wouldn't allow you to create. But if someone has a better tool out there, I'm all ears as well.

I use atom IDE for both SuiteScript and freemarker, the freemarker support isn't great, but it's got a similar functionality like bracket matching (something like tag matching) The change in colors also help! You can change the syntax in the Atom IDE, to say from javascript to freemarker, then you get a little bit more support 🙂
