So what they set up are macros which turn 3 of one type of inspiration in to a more desired type of inspiration. Each macro will have the image of the type you are converting.
So if you use, for example:
/macro_image Inspiration_Damage_Resistance_Lvl_1 ORANGE insp_combine "Sturdy" "Luck"
It will create a macro with the image of a small orange inspiration, that when clicked will turn all small orange inspirations you have in to a small purple.
I believe it's possible to make a single macro that will convert all 3 sizes, as I don't think it over extends the limits of a macro- it would look like this:
/macro_image Inspiration_Damage_Resistance_Lvl_1 ORANGE "inspcombine sturdy Enrage$$inspcombine rugged focused_rage$$inspcombine robust righteous_rage"
Which should turn all oranges in to reds
I use a popmenu bound to E, that hitting e turns all my unwanted inspirations to reds, hitting r makes me much a red. Though, I might just put the use command in the combine command, then I can just spam e >.>
Concerning the popmenu thing - would you be willing to share how you got about setting something like that up? WIth the hit 'e' to convert, 'r' to munch. That sounds super cool :O
