I edit way more than just source files. Usually I just edit .txt files. If I’m in the Cinnamon desktop environment and not just the terminal, I’ll open up SciTE. However, by default it shows just source files, and I always have to switch it to show all files.
Here’s how to do that.
Get SciTE to show all files in the open file dialog on Linux
Edit the file SciTEGlobal.properties, probably /usr/share/scite/SciTEGlobal.properties
if PLAT_GTK all.files=All Files (*)|*|Hidden Files (.*)|.*| top.filters=$(all.files)$(source.all.filter)
You can see that you can modify the defaults for other platforms as well. Voila!
