Add the GIST API to the script explorer
Add some level of source control. I would like to have the gists API integrated directly into LINQpad. Because basically gists are scripts.

I gave it a vote, but add that rather than lock in to GIST API, make management of "My Queries" into a "pluggable" feature.
LINQPad probes the folder it runs in (or previous versions ran in) for an assembly that implements an interface like IUserQueryManager or similar and then loads that on startup to handle query management features like retrieving the collection to show in the tree and load / save scripts.
That way, you could use anything as the backing store for your scripts.
