I am a regular user of SO and other stack sites. and found it can be better if we can have some functionality like choosing unanswered questions which are of mytags and are newest..
I mean we have filters over there which filters question based on one thing either
unanswered. there should be multiple selection which filters a lower deeper for say newest with mytags.
and also while selecting by votes it can have range of votes to chose from..
I hope this feature will make it more user friendly.
