KetaiList

Hi. I copied the KetaiList class into a new processing tab to be able to customize it. But I only managed to change the backGround color. I tried to set textColor and do some padding, but although it doesn't give any errors, it also hasn't any effect. Any idea what is wrong? Thanks in advance
