The predecessor to Level Design Tool Kit is Live Level Design. This asset takes some of the key features from LDTK and compacts it into small and dynamically changing EUW.

Only tools that can currently be used will be displayed. For example the "Calculate Distance" tool requires 2 actors to be selected. So if 1 or 3+ actors are selected, the "Calculate Distance" button is hidden to prevent culter on screen. The same principle is applied to all tools. This results in buttons only being displayed on the EUW when they can be used.

Note: The EUW requires the "Editor Scripting Utilities" plugin. The GIF below shows you how to do this if you haven't already.
