What do you search for in the Gallery?

I usually go into the gallery and look for whatever it is I could use for my game at the time I am playing it. I sometimes need a new teen for the neighborhood so I look for one and then put her/him in someone home and then have her/him in the neighborhood. Sometimes I need more so my teen sim can choose his preference. Also I do this with other sims depending on what I need. I have taken an elder sim I liked and made them in CAS be a younger sim or even some adult sims I changed to teens. Just depends on what I need at the time and when I do this I get them skilled so that they fit into the game and are not playing catchup really it does not matter what they look like or the traits it is by what I need at the time as long as they are skilled and I then put the first one I see that may fit the situation into my game.
For houses and buildings I usually use ehaught58 as his builds seem to fit my playing style.
