I think it would be nice if you could link reports somehow in Wabit. So if I have 5 reports created, the 'master' report could somehow have hyperlinks to the other subreports. Right now, Wabit can really only customize columns, but this feature would require a properties panel for individual records.
This is something that we have actually talked about in the past. In particular, if you wanted to make a summary report and have it link to other reports it would be very useful to be able to click on the report and have it switch to the next report for you. I've filed this as bug 2365.
