From what I understand, there are pitfalls using his addons. I accept that.
But no one is working on an addon without these pitfalls.
This is typical of XF. It takes a lot of addons to emulate features that we need. But it is tough to get legitimate coders interested in providing those addons at a reasonable cost.
Sure, you could pay a legitimate coder 3000 pounds to do it if you could afford it. But not many can afford that, I would bet.
