i agree that the arrows are completely unnecessary. they're just built in to html5, though, because the deposit/withdrawal boxes are number inputs now instead of text inputs. afaik you can't remove them. they're not a special feature we added, it's just something built into your browser.
they do a setting, though, that i could make them do more than 1 at a time, but the major caveat to that is if you use that setting (unless the documentation is just really unclearly written), only amounts that you could get to with the arrows are valid to submit. like if i made this setting 2, you could only submit even numbers. if it were 3, you could only submit multiples of 3, etc. so it kinda has to stay 1.
You can just click your sP amount to get to your currencies
the link is still on the dashboard. same place it's always been. your onhand sp total. :)
