Checkbox for Texture Search Lock + Checkbox to apply textures on all block faces

Hi everyone,

First, I would like to thank you for the incredible work you do for years, I really love what you're making :)

I'm making a mod with many, MANY block, and so with MANY textures. I imported all of the resources needed, and I began to create all block. The easiest method for me to do it faster is to dupplicate the previous cube, which contains all good properties. 

And now here is my 2 problems: I have so much textures that I need to scroll down each time to find the good textures, between wood, stone, ... So it would be great to put just next to the search input, a little checkbox to lock the search for the nex time you would use it. I could with it directly find the textures I need without typing again what I'm looking for, a lot of time would have been not wasted :)

And the second idea that would help me a lot when I dupplicate, is to have another chekbox to update all faces of the block, because when I dupplicate the previous block, I already have all faces which have been set, and I have to change it one by one, that's a lot of time wasted :(

I hope you'll understand, sorry for my bad english.

Thank you again for all you do :)
