HTML5 Multitool Layout- Arrow size too small

The new multitool at GVH 2.4 is wonderful as a space saver for smaller devices.  But I find the dropdown arrow is too small to tap on for me even in the office (and I have small fingers!). The toolbar row is about 100px, but the height of the button that controls the dropdown is less than 21px.  Please consider improving the UX by maximizing the height of the dropdown button so users miss less!
