Need a buff tracker that doesn't track everything, and tracks Rearming trap...
 

I can't fathom why FTC does not display Rearming trap buff, but will show every single other buff including ones on other people...

I know there was an addon you had to manually type the ID and stuff in, but I could never manage to get that addon to show Vigor at the time.

Does anyone got an addon that can do this? I want to see my endless hail time, poison inject, vigor, rearming trap, rending slashes, etc...

Try Srendarr, look at the description page how it works and find videos online with Google for examples.
I think it should be enough for your needs if you take some time to understand and configure it correctly.
If a buff is missing you can contact the addon author and write a comment what is not working or is misding, and I bet he'll help you.

I don't know any other simple and configurable addon like Srendarr.

short version:

1. use s'rendarr
2. only activate prominent bar
3. config prominent bar
4. add ID's to prominent bar

you can find id's from: esolog.uesp.net/viewlog.php

thanks buddy
