Build/buy mode has too much stuff

I also do a lot of building, and I own most of the stuff, game, and expansion packs, so I agree we need some more options for hiding, grouping, filtering, and searching.

- The filters resetting when you use the eyedropper tool is one of my biggest frustrations. There needs to be a way to "lock" and "unlock" filters so that we can use the eyedropper tool without losing all the filters we selected. Or just fix the eyedropper tool so it doesn't reset filters.

- The search function is almost useless because you have to actually remember what cutesie name the writers decided to call the object. Searches for generic terms like "wooden barrel" don't work if those exact words aren't in the object's title.

- It would be really helpful to be able to designate our own custom "collections" of items, like we could in Sims 3. That way we could flag sets of items we frequently use together according to our own needs.

- It would also be very helpful to have a filter for hiding cc when we want to only be looking at official items (for example when building stuff to go on the gallery). Note: I have been using Twisted Mexi's better build/buy mod for this (and a few other build mode improvements) but I think it ought to be a filter in the official vanilla build mode.

For anyone who uses mods, I do recommend the "Better Build/Buy" mod. It makes a lot of things easier and more intuitive for heavy use builders, and I love it. But the vanilla game build mode could really use some improvements to make things easier to find when you have a lot of stuff.
