I'm sure most of you already use this to your advantage but in-case some are un-aware or "forget"..........
I find that my overall performance has been hindered for to loooong, (and it's annoying) deleting / renaming / reordering draft envirnment TABS by right clicking the current tab then selecting the desired action.
Setting keyboard shortcuts for these has taken some of the annoyance out of permorming these actions. Hope someone gets use out of this!!!
