It'd be really nice if we could customize/toggle what buttons are shown in the actual toolbar vs in the "More" dropdown. I don't use all the ones in the toolbar, but I do use ones that are hidden in "More" (especially Priority and Task Type). Or the option to toggle off the names of the buttons and have more icons show in the toolbar at once? It'd also be nice to select specific custom fields to show, not just Custom Fields as a whole (which requires clicking in, selecting the field, then selecting the value).
