I think just like most of other software, VBAI should take the last selection as the default value for this type. This what I mostly require in Custom Overlay steps.
Mostly we are using the same text type-color etc. for different elements but because VBAI changes the color randomly, and making the size 13 every time, we have to change it for all elements. Since generally I use one color for most of the text list on the screen, it would be really helpful if VBAI could remember my last choice as default for the next selection.
