I really like the layout and overall appearance of the main UI. The combat log filters are great and will be a wonderful tool for post-fight analysis... Much, much easier than an F3 search on TORparse.
The one thing that I've noticed that TORparse has that Parsec is missing is a pop-out for the "Damage Dealt" info, which is quite handy for on-the-fly tweaks while on the dummy. Will see if folks are willing to try the raid parsing with this program tonight, but it looks like that will be a simple process to setup; it's just a matter of how well it actually works.
Try the statistics overview, will display dmg dealt as well as dps, along with the length of the parse.
