Is your feature request related to a problem? Please describe.
Well you can say that my problem is that I cannot create a resource bar for anything

Describe the solution you'd like
Would be great to have a "Resource type" of "Lua", so I can provide my own data to the resource bar. For example, I have a trinket that stores some extra healing, I could check how much is stored but that would require to move the cursor over a buff

Describe alternatives you've considered
Not much, maybe use a group controller icon and show some amount of icons to represent health stored?

Additional context
No, I only would like to feed the resource bar with anything

Same here: It would be very nice to have the rest amount of "Ignore Pain" (protection warrior) as a bar. Actually you can only display the amount as a number.
