I posted the same question before, but got ignored. I guess there is no such option.

Topic: More entries per inventory page (0 replies, posted in Site Discussion)
Hello,
is there any possibility to change the amount of cards displayed on one page in the inventory (list view)?
I am fairly new to magic in general and have added just about 80 distinct cards to my inventory at the moment, but the list already expands over 3 pages, since it only gives me 30 cards per page.
I know there are filters if I am searching for something special, but I generally like big Lists for sorting stuff.
So if I am just overlooking the right button, please enlighten me. 
Thanks in advance
