Can we/should we start an official iOS feature request thread? Until then...
Right clicking is a pain when you have to hold down your finger and browse through a menu. A simple toggle click on, toggle click off would be easier. It's tough to navigate to the discard random X cards and press the correct number when your finger is blocking the tiny number buttons.
Also, when you load a deck that has many tabs (Space Hulk Death Angel plugin for example), you can't scroll the tabs to see all of them in the deck editor.
I will make a new thread for the iPad version once I officially announce it. (Waiting on the SLOW process for them to post the version I uploaded on the august 8th.)
I'll look at ways of making the scrolling of lists better. But remember there are many different ways of doing everything. For discarding X random cards, I suggest you double-click the corresponding game-zone tab and use the dialogue there. Check the game play tutorial video if you don't know about that.
Regarding the tabs not fitting, I have a few comments. First, this shouldn't happen since it should form additional rows as needed, so there is indeed a bug. I never tested a plugin with so many different deck zones. As a quick fix, the plugin maker could reduce the length of the name of the deck zones. (Instead of "Event deck", he could call it "Events" and instead of "Location deck" he could call it simply "Locations". Labeling any deck zone as a "deck" is a little redundant.)
On iPad, do things fit if you put it in landscape? Some things look better in landscape and some things look better in portrait. On iPad, I find myself switching often for a different layout.
The iPad version I posted that is not yet live allows you to change the font size of things, and therefore how large the buttons are and therefore how the entire interface is spaced. So once that is live, that might help.
