This tip is very simple, but I find myself using it all the time now, so I thought I would share it.
Create a new Bible Word Study and add only the "Root" tool. I named it "BWS - Root".
Now, when you right click on a word and select Lemma, you can very quickly do a "Root" study, with no need to scroll down to the Root tool. This is extremely useful to get a feel for the semantic range of a word.
Here is an example of how this looks (although in this example I am right clicking on a Hebrew word, it works right clicking on a word in the Reverse Interlinear English Bibles as well):

Now the "BWS - Root" Bible Word Study opens right to the Root tool, with no need to scroll to compare all the roots and get a better feel for the semantic range of the word, learn new vocabulary, etc.

Now we just need Logos to allow us to "Send hyperlinks here" for Bible Word Studies, so that a new tab isn't opened each time a BWS is opened.
