UI Builder needs horizontal layout and scalability

I can't snap visual elements side to side without turning on absolute mode? how am i supposed to create neat looking property fields with this if everything i make is 3 rows. note: i am using 2019.2.17 but the ui builder seems to work and run. i just want my label| drop down button for options| field to be possible to make with the UI builder. otherwise it seems kind of useless even for making game menus... Try to make an inventory system where you can't scale up or down just because... am i just too dumb to find the percentage sign?
