I realize that some of what I am about to put in you can already do, I'm adding in keyboard commands anyhow just because I am all for different ways of doing things. For instance, if you know the name of an object, you can type a command in some cases faster than finding it in the list and arrowing down the menu and hitting enter.

Same with follow. Some stuff I will put in not so well-defined, because it's lower on the list and I haven't got all the interface worked out in my head yet.

Some of this is hard to prioritize, but I'll try.
1. go
//go name=Person's Name
//go object=Object Name
//go distance (//go 5) moves y ou gthe set amount of meters.
//go distance direction (n s e w ne nw se sw)
//go xyz=x,y,z (you can just have it ignore the z coordinates if you're not flying. Reminds me I need to play with flying.)
2. face
//face direction (n, ne, nw, e, w, s, se, sw)
//face degree (//face 260)
//face name=Person Name
//face object=Object Name
3.. Improve follow, add //follow Person Name and //stop to terminate follow. 
4. Improve object and people list to tell you what direction they are facing in addition to the distance.
5. Ability to edit SL profile.
6. Building commands. moving objcts, resizing them, changing color and texture, creating objects, for that matter.
7. Inventory--ability to rename rezed objects that you own or are allowed to modify.
8. SOUND SUPPORT! By sound support I mean ability to hear in-world sounds that you can get with the standard viewer. You know those environmental things people sometimes put in their spaces to give it more a sense of realism.
