Yep, the website is being kept simple, in fact too simple and will have to be eventually redesigned. It seems the classic (and actually up to date) WinAPI GUI shouldn't imply the software is being "slow". One could have it both ways and say it's usually on the contrary where commonly cloned packages weighing hundreds of MB and performing relatively simple tasks get a free ride on users' ten(s) of times faster hardware. Then there is the Wirth's law, May's law etc.
