Please find some explanation regarding your comments below
1) OQL query browser - The way the browser works is that we load the compiled assembly (and other referenced assemblies) for the project in a new AppDomain and execute the specified OQL query. The browser requires the assemblies to be built. Making the dialog modeless would mean that you cannot make some changes to the sources while the browser is open, compile and use the browser with the compiled changes.
What is the information that you frequently need from your VS project? Maybe we can provide that within the browser so that you don't feel the necessity to go back to VS. Regarding the query file name and size and position, we will definitely implement those suggestions.
2) Reverse mapping - The 'Select All' option will be available in the next release. In the meantime could you use 'Ctrl+A' within the grid to select all the rows and then check the 'Generate Selected Classes' checkbox. I agree the wizard is not easy to use with source controlled files. This is a scheduled item and we are actively working on implementing a solution for this.
