Snippet window suggestions

Some suggestion for the pop-up snippet window (Win 7) that would be very useful:

1. make the window resizeable

2. make the window pinnable/dockable

3. order the columns, i.e. trigger first, description second

4. add columns through the snipet xml, though this may make it incompatible with textmate format

4. able to sort the snippet list alphabetically by description

Thanks
