I'm really glad you like the addon.
For the first question, if you want a vertical slider, the only option right now is to rotate the pose bone by 90 degrees.
For the second question, if you're imagining a centered handle that drives different parameters depending on whether it moves left/right or up/down, that isn't possible at the moment. If enough people want this feature, I may consider adding it in a future update.
