LyX Developers, I recently submitted an enhancement request through the bug tracker and it was suggested I post here to initiate discussion on it. The TRAC ticket number is #9966 <http://www.lyx.org/trac/ticket/9966>.
My suggestion is to change the default font of the Settings->Preamble text box to a fixed-width font because the content is effectively code. This change should improve readability for those that make extensive use of the preamble. Going a step further with the topic: would it also make sense to disable (or make optional) line-wrapping in the preamble dialog? I would appreciate hearing your thoughts on this. Thank you, Joel
