I buy a bunch of specific insps and email them to myself. That way if I am in a mission, I can access more of what I need if my tray runs low.
For key binding, I try to use a letter that I can easily associate with the power...F for fly, H for heal, P for telePorting friends, etc. Makes it much easier for me to remember...
/bind F "powexec_name Fly"
/bind P "powexec_name Recall Friend"
/bind PageUp "powexec_name Resurrect"
/bind O "powexec_name Ouroboros Portal"
/bind Z "powexec_name Super Speed" (ZIPPING around)
/bind T "powexec_name Taunt"
etc.
I use the F-keys for my toggle powers. Pet summoning, Blazing Aura, Arctic Air, Danger Sense, etc.
I use my Vault (not regular salvage) to store extra uncommon/rare salvage, and use a macro to bring it up. Then, they can be transferred from vault to regular.
/macro VLT "$$ toggle vault"
I keep my UI windows clear so I can see more of the screen.
