If your front panel is so large that the user has to scroll up/down, left/right to see everyting, it's probably too large. As a rule of thumb, I design a front panel so it fits an 800/600 screen. Things like the tab control, pop-up subVIs, and sub-panels make this possible. I would suggest you start with Chapter 6 of the LabVIEW Development Guidlines (Help>Search to LabVIEW Bookshelf).
Using the same indicator on different scrolled locations is possible because you can programatically move it but it's pretty involved to get screen position, etc, and move something back and forth.
