Using float numbers for opacity prints error

[Andre601]

Using any kind of float number (i.e. 100.5) for the opacity/alpha causes the below error to be printed on reload.

The plugin should have some measurement in place to either deny the loading of such invalid numbers or correct them (i.e. round them to the next whole number)

Error:

Currently there are no checks for the correctness of the config. The error can be caused in any point of the config most likely. Maybe I'll add checks later
