I was looking to know if there is any alternative IDE for arduino.
If you run Windows, you would probably be happy with a good text editor such as EditPad Pro
( http://www.editpadpro.com ).
It has syntax highlighting, brace matching, line numbers, search and replace, full regex support, etc... everything you need to manage your source.
Then, use the Arduino IDE in "external editor" mode solely to compile and upload the code.
I run Linux and use Kate (KDE text editor) to write Arduino code, then use the Arduino IDE just to compile and upload.
(btw, I am not affiliated with EditPad or JGSoft... I just have experience with their editor and highly recommend it).
