I got really used to hitting the tab to add a new node by typing in the search field and then selecting from options. This works in tyFlow plugin and similar process can be found in other software packages like Unreal engine's material editor etc. So it would be nice to have it inside of the slate material editor.
Right now there is a option to search from the left collumn and then drag and drop or right click or drag from existing node. These are almost there, only if the had that option to type in the searched node name.
