[otrs] Which DTL and which CSS for which webpage?

Hi, I'd like to change several small layout and output details in OTRS (e.g. more/different columns in the Dashboard, top-aligned rows and bold ticket titles in the QueueView etc.). Finding the right DTL and CSS files usually requires lots of timeconsuming searching with `find`/`grep`. Is there an easier way to find out, which DTL and CSS files are used for which page and which datafields can be used within a specific DTL? I looked for this kind of information in the Admin Manual to no avail. I'm currently using OTRS 3.x on Linux. Cheers frank
