Move type definitions into WConstants.h.
Change core and libraries to use Arduino types (e.g. byte, boolean).
Fix millis() so it never increments by two.
Consider moving millis() to timer 1, and configuring it so the interrupt is generated once a millisecond.

COMPUTER

Check RAM usage of sketches: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1224729260/0#0
Improve preprocessing of sketches:
 - Better determine which header files are included (not commented out).
 - Remember the original locations of function prototypes to highlight the correct line on error.
Multiple sketch windows.
Avoid library conflicts by only linking in the library whose name matches that of the #included header file.
Easier library discovery and installation ("Add library..." menu item).
Easier board installation ("Add board..." menu item)
Comprehensive board management:
 - Enabled and disabled boards.
 - Dialog for enabling, disabling, adding, deleting, and possibly editing boards.
 - Board descriptions (e.g. explaining differences between boards).
Allow for libraries in <SKETCHBOOK>/libraries.
Allow for boards in <SKETCHBOOK>/boards.
Divide boards.txt into multiple text files.
Allow for core in <SKETCHBOOK>/cores.
Clean up Library and LibraryManager.
Compile libraries dynamically (with compilation of sketch and core files).
Detect dependencies between libraries.
Byte-based serial monitor.
Line termination options in the serial monitor.
Clear character should clear serial monitor.
Incorporate serial-net proxy.
Changing font size should change serial monitor font size.
Deal with shorter screens (e.g. ASUS EEPC).
Investigate method for auto-detecting serial port on Windows (javax.usb?)
 - http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1225226642
Guess serial port on the Mac and Linux.
Automatic detection of baud rate for serial monitor (based on the call to Serial.begin() in the current sketch).
Improve, generally, the upload experience (e.g. faster program start after upload, keep-alive messages to bootloader from IDE, shorter bootloader timeout if possible, progress bar)
Allow uploading of .hex files.
Allow for arbitrary compilation command line arguments.
Find in reference should give same message for missing page as for missing page association.
Test find in reference on libraries.
Change background color while using external editor: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1229567785
