Hi - I haven't used arduino for a while. I have mainly been using Dev C++, Visual Studio and Eclipse.
Boy the Arduino IDE needs work.
First of all, the indenting is broken. If I do a tab in VIM compared to arduino the result is totally different. (Arduino IDE barely indents) Code readability suffers greatly. This is so bad, that I use VIM instead of the IDE now.
In the external editors options in preferences a crucial option is missing.
You should be able to specify the location of an editor and have it load up with the arduino editor if the use external editor option is checked. This should be an easy fix. Also nice would be an option to reload the file.
Other suggestion: Maybe have the IDE have a VI and/or Emacs mode where you can use their key bindings to move around faster in Arduino IDE.
Thanks!
