Consider auto indenting settings additions
It would be nice to get automatic indent after some structures like "then" and so forth. Typing in this mode and having to hit tab a lot has a strange feel to it, so it's something Emacs vhdl-mode was likely doing automatically.
Yeah this feature is going to take a lot of experimentation to make it work in a way that feels seamless.
This feature can be implemented using a TextMate setting file. Here's an example: https://github.com/SublimeText-Markdown/MarkdownEditing/blob/master/Indent%253A%20Raw.tmPreferences
Well, I know there's a method. The trouble was that nothing I tried felt natural using it. I haven't looked at this feature in a long time so perhaps when I get some opportunity, I can take another crack at it.
