First of all, these tools are so similar that they need to be combined somehow - in the very least, it should be possible to launch them together as a set when creating a new layout.
Secondly, and this is my main issue - I do most of my reading and close study (when I actually need these tools) away from the main set of panels of the application. In other words, if I want to take a close look at a particular resource, I will open that resource in a "floating window" to get away from the distractions and space constraints of the main application window. But the "side panel tools" remain tied to the main app window - as far as I can tell, there is no way to drag or otherwise move these tools to my floating window.
Would love to see the panel tools made available to floating windows and would love to see these tools integrated or connected in some way. (Perhaps there should even be an option that causes them to open by default.)
