I've been doing quite a lot of work in QML lately for one of my research projects. Recently, I ran into some problems when trying to use ShaderEffects to actually apply them to "interesting" widgets/elements (i.e. on to anything that's not an Image and/or is more complicated than just a simple Rectangle). This post is just a quick guide to some of the key issues here (and ways around them), since it's not exactly that obvious from the documentation that this is the cause/solution, and no other hits come up about these issues...

Useful Tip: Changing command line prompt on Windows
I just came across a useful little trick this afternoon for making the Windows command line prompt (i.e. the one you get when running cmd, which shows the current directory) much shorter (heck, you can set it to anything you like even!), so I thought I'd just note it here so that I can look it up again should I forget in future.
That's it! Just type this little command, and it will change the prompt that gets displayed.

Annoying Habits of Computer Science/Software Engineering (Students) Designing UI's...
Over the past few years, I've had the opportunity to have a front-seat view of how groups of 3rd year computer science/software engineering students approach the problem of designing a UI. It has been said in a few places (citation needed) that ultimately, the way group projects end up taking place for class projects and in real life are largely similar(ly awful). Thus, given that many of these folk will end up in the workforce in the next few months to a year's time as the newest batch of "professionals", if what I've seen is anything to go by, no wonder we're kindof perpetually doomed...
It's also no wonder then that we're often burdened with so many absolutely terrible systems for what-should-be-mundane/trouble-free processes like activating cards or making use of various services for the first time, etc. Or, nastier problems like the current religious dogma + regime of "automatic software updates" that regularly foist themselves at you every other day, usually at the least convenient times, and from time to time leaving a colossal mess behind when they're done.
