I'm on Geany 1.33 on Debian Buster and I was looking for a way to save these files in `/var/tmp` so that they are preserved between reboots or system crashes. Defining `TMPDIR` really works, but setting it to anything other than '/tmp' for all applications is generally undesirable. The user would normally want to configure it only for Geany. This requires modifying the files that are managed by the system's package manager (the desktop shortcut or the executable, which must be replaced by a script that defines the variable and then calls the executable), which makes updating Geany and the entire system complicated and prone to errors. I would like to ask for these options in the Instant Save plug-in configuration panel:

- Default system temporary directory - Custom directory: `[input field]`
