And to be clear, Geany is intended to be fairly easy to use, and to not have the steep learning cliff of Emacs or Vi.
But Geany is not specifically targeted at first time programmers either, in general it is expected that any programmer with experience will be used to looking stuff up, and can edit configuration files. So its never been a priority to have every setting appear in the preferences GUI or to be perfectly configured by default for every use-case.
