You forgot to list that you need to have the Code (Text): booster.place permission to place the signs Otherwise, great plugin, we're using it on the server at our spawn!
I found a bug. Values can't be higher than 4 but you can do -100 (I think that should be limited to -4 too?).
okaay updated BoostPads with a new update entry: Fixed minor bug whilst entering values Read the rest of this update entry...
This plugin still throws some errors but appears to still work perfectly in 1.12 through 1.16.1. We've used this for jumppads on our server for a while now and never had any problems from the errors that are thrown so they do not seem to have any impact.
