- function / loop / condition collapsing
- zoom-feature (font-size change -/+ by button)
- code completion (suggestion)
- function / class tracking-window (position and calls)
- variable tracking window (this is easy in php, but hard in other languages, I suggest to let the user define what a variable is (right-click?) and implement a self-updating search function (when editor idle):
"var_1" - lines: 5,43,234,255
"var_2" - lines: 4,243,322
- code formatter (careful here, if you do, make this very customizable and allow step-by-step conversion, all versions I have seen just run through, many corrupt the code)
Additionally I would like to see an option to call (or even display integrated) a user-defined website, there are many tutorials and function overviews on the web, but require some window juggling.
Thanks for the work you all do, please let me know if you need more details or examples/screenshots.
