The diary program I use for my journaling is Diarium (yes, I’ve talked about its unfortunate name before). It’s available on pretty much every platform, save Linux (and web). Unlike many people, I don’t write in the diary on my mobile devices, so I’m usually using the Windows or Mac version. Both have slight differences in UI, but generally work the same.
One key difference is fonts. The Windows version lets you use any font you want. I am using the new MS Office font, Aptos, because I like the way it looks. The Mac version only offers a small subset of fonts and I have no idea if this is just the default setup for any Mac program and easier to program or what, because other apps, such as Affinity Designer, will show you all fonts.
My point, though, is that when a program gives me a choice of fonts, I want access to every font available. If I want to write my journal in Papyrus or Comic Sans, let me! The Mac version of Diarium won’t let me and it makes me sad. π (I would use Aptos there, too.)
Anyway, this is my plea to app-creating wizards and gnomes: Always let the users choose from any fonts they have installed. It’s the nice thing to do. Also, make a Linux version, or at least make the Windows version behave nicely under Linux.
That is all.
