With the increasing number of apps from great developers (you know who you are!) keeping track of updates is getting more challenging as well. (Yes I know I can install HPM but not every dev may support it)
I would like to make a suggestion that the user apps/drivers section of the HE web interface could include a version column as well so we would know which ones are installed. Similarly devs who host code on github can simply include the version number in the app description like @gavincampbell does with Fully Kiosk Browser.
