Re-reading Thrawn (2017) while also doing a watch through of TNG, so I found this comment on comlink badges particularly funny

Text in photo:

'"It would also be useful to arrange the comlinks so that one would not need to draw them from belt or pocket."

"That would definitely be handy." Vanto gestures to the lieutenant's rank plaque. "Maybe you could put it inside the rank plaque. At least wouldn't have to worry about dropping it."

"Could that be done?"

"What, put a comlink in the rank plaque? Sure.'
