I can no longer see 200 cards per page in my inventory or wish list, and I can't find the option again, as if it disappeared. Anyone know where I can find that option or shed some light on this?

I'm currently stuck viewing 25 cards per page.

You probably had a trial Premium account.

Thanks for the information, yes I was on a trial premium account. I wouldn't have thought that seeing 200 cards would require a premium account.

Yeah, there are a number of things like that. Most of the time I don't bother with premium. Sebi was really good about features and fixes in the past, but development has really stagnated in the last year or so.
