Geany is a nice GUI option. It’s a bit more capable but still lean.
It’s probably time for me to re-evaluate the host of coding editors out there. For the most part I just use good text editors. Though I do love Spyder, I only use it for a certain subset of tasks.
Kind of the opposite. It takes more effort to make a filesystem case-insensitive. Binary comparison is the laziest approach. (Note that laziness is a virtue.)
I’m on the fence as to which is better. Putting backwards compatibility aside, there’s a perfectly good case to be made for case-insensitivity being more intuitive to the human user.
Apple got into a strange position when marrying Mac OS (case-insensitive) and NeXTSTEP (case-sensitive). It used to be possible to install OS X on case-sensitive HFS+ but it was never very well supported and I think they axed it somewhere down the road.
