Almost everything can be made from a NAND gate and the things that you can’t are in the library (Clock, Displays, Tri-State Buffer.) Just google how to make not gate from NAND then take a NAND and invert it to get an AND etc.
CTRL+S or MENU > SAVE New chips start in the "Other" collection - you can use the JUMP UP/DOWN and MOVE UP/DOWN on the chip in the library screen to move them around between collections.
