To my knowledge, CoX has two different ways to view information about a power without going into a full overlay menu:
1) Open your Powers menu and right-click the power.
2) Mouse over the status icon of the power in the top right corner and right-click.
These methods differ in a way that hides some information from players. Most importantly, option 2 will not display the remaining duration of a power. Doing so requires option 1, which covers part of the screen, may require scrolling down to find the power, and requires an extra click total.
As a returning but inexperienced player, this discrepancy adds a barrier to finding information quickly. For instance, I do not know the remaining duration of a day job effect or buffs from other players without going into the Powers menu first. I would like the duration effect to be included in option 2, unless it cannot be due to engine limitations.
