I have made several requests about "accessibility" or "ease of use for newbies," which some may want to call "intuitiveness."
Here is a summary of those of my requests which are not found in CT yet, but may awaken in the users interest in a possibly higher level of usability (= laziness).
Just one note. Maybe I misunderstood you, but
Point 1. this works at least from the glossary windows (I assume you are using the glossary bar), but one click should indeed always insert the whole glossary entry (if consisting of more than one word) – this would be nice
Point 2. this works from the grid, and a double-click from the source segment could easily/accidentally interfere with simply marking a word to search or filter for it. I prefer the actual behavior.
