The search is quite useful, but it does take up a bit of permanent screen real-estate: Can the search bar be rolled into the side? Or be a drop-down list?
If it is to remain, then it would be even better if there was a preview square beside each material.
It would also be really nice if the general tab had a preview of the material as it would actually be displayed within the Enscape window (Perhaps on a sphere or box or something?)
Hey @Gadget_1 , thanks a lot for your inquiries. 
I’ll gladly file them as feature requests accordingly. Would you prefer being able to roll the search dialogue to the side, or have the materials selectable via a drop-down list?
Also let me know if there is anything else you want to add.
I think that rolling it so that the user could “pin” the search out would have more use than a drop-down (un-pinned, it would still function like a drop-down)
