What is the problem that needs to be solved (required)? Currently the Exe selector requires that when the executable is updated (new nightly, new release, etc) the user has to select a new executable.

What is the idea in abstract terms (optional)? Add two new selections to the the executable box "Newest Release", and "Newest Debug" to select the most recent release build or most recent debug build. Also could have "Newest Official Release", "Newest Official Debug".

Good idea. As I see it we have four droplist items that should always be present:

Newest Official Release Newest Official Debug Latest Nightly Release Latest Nightly Debug

Below those, we list the current binaries that are present in the mod root folder.
