stable & beta

Usually everything that is enabled by default it means it has been tested enough and i have trust it will work.
Anyway, each mailwizz release is stable, the fact that bugs appear doesn't make it unstable perse, it's just the way things work.
Sure, I did not mean any implication, rather, users need to be aware which parts are heavily tested and which ones are newer and less tested. After all, life (real world usage by power, average, and occasional users doing all kinds of things) poses different tests than (quick) lab test with certain standard procedures (that are inherently rather similar, as coming from similar source) than the vast diversity of users does.
This is meant to help ;)
