The new Yosemite (v10.10.1) Preview (v8) is using 2gb of RAM when the app is simply open (no files/windows open yet). Any way to reduce that (my macbook only has 4gb total)? Also a lot of changes were made to how text is added to pdfs and it is so slow now, any way to return to previous versions of preview? Thanks!

I just opened my Preview app and then Activity Monitor to check its RAM use. The answer: less than 10 megabytes! (My machine has 8GB RAM.)
So I suggest you close Preview and reopen it.
Back up all data. Quit Preview if it's running.
Hold down the option key and select Go ▹ Library from the Finder menu bar. From the Library folder, delete the following items, if they exist:
Containers/com.apple.Preview
Group Containers/com.apple.Preview
Preferences/com.apple.Preview.LSSharedFileList.plist
Preferences/com.apple.Preview.SandboxedPersistentURLs.LSSharedFileList.plist
Saved Application State/com.apple.Preview.savedState
Log out and log back in. Launch the application and test.
Now running at 72MB while open (no windows open though) so it has improved things, thank you.
