Hello, i plan to use a file that i will include on each widget with all variable i may need with my skin, my problem is, i guess, variables i don't display will still eat ressources.

Also, if i important the same variable file on multiple widget files, will the measure be calculated one time per widget, or once for every widget ? If not once for every widget, is there a solution to allow that ?

Regards
