It's possible to re-name the files so in that respect you might be able to re-organize them in the album. You can also manually split or combine the files yourself. This is handy if, for example, you did the scene detection by video content rather than time codes. Studio can interpret a camera flash as a scene change when it actually isn't. None of these options actually splits your original captured video, that always stays intact. All that happens is the .scn file (and maybe index files) are updated to reflect your changes.
However, the program I use, WinDV, does have an option to create separate avi files as it's capturing. I never used it because I didn't have a need for it.
I don't know of any specifics on the plugins for displaying the date and time. I looked through the ones I have and it wasn't listed. Perhaps someone else can point you in the right direction.
