I would really like to be able to create my own syntax field (or edit them) form within the app - for example, Microchip PIC assembler and PIC 32 (MIPS) C functions. Ideally this would be a simple GUI. 

Also would like to be able to set my own colours form a 'settings' section

Using Mavericks on Mac

thanks
