I don’t personally care about customisation, but if it’s offered, I’ll usually customise or at least partly customise.
I prefer basic customisation. I read on a tablet. Some creators take that into consideration, but some don’t, meaning that I can’t tap on everything lol. Even the templates that do take my tablet into consideration can sometimes be buggy- it can be hard to tap things at times. I also find it takes longer if you need to tap through options. I know what I want. I’d rather be able to go straight to that option and get the CC over with lol
