I love this! Sounds great so far, the customisable keybinding for prayer, and inventory will be very useful for me. However can you explain what you mean by "main management interfaces" I get that the F1, F2 and F3 will link to them, but what are they?
I ask because on my laptop (HP Pavilion g6) the F keys can only be used with the fn key as in 'fn + F1' for inventory, which is a pain, meaning that I currently don't use F shortcuts to open prayers, inventory etc because F1 opens "windows help and support", so if I miss out the fn key at a boss for example it opens a window over runescape and I've had a few close calls due to it.
Essentially I want to know what the main management interfaces are, hopefully not something I'll need to use frequently.
