tags not retroactive and list of used programs/websites in activity view

hello. the activity name one makes is not retroactive? whenever i add an activity, it doesn't record any time i had used the respective program or website from before i added the activity. it's a feature that's important because people can go off and do things throughout the day on certain pages and programs and not realize it's not being recorded. that means people need to make the activity BEFORE they do work. one needs to anticipate what they're going to do before they do it, which means if you don't....all the time put into the specific program or website won't be recorded. am i correct? also, in the activity view, instead of typing out a title of a window or website, there should also be an option of a list of past viewed/used programs and websites. these are two features that would EXTREMELY enhance the power of you program. next release?
