I was reporting a lot of bugs to them initially, but so many of them were ignored that I can’t force myself to do this anymore.
I’m still paying for IDEA Ultimate, but it's only because I’m waiting for a better IDE with a more fair subscription system (when I cancel the subscription that was at least 1 year long, I should have the LATEST version I’ve paid for, not the first one). I will try Feet, of course, but I have no high hopes nor trust for JB.
