I guess if you're used to Jellybean and above it can seem impossible

The NST was my first Android experience so I see its limitations a little differently (I now also have a CM 12 Nook Tablet, so I see both sides). I honestly don't get the whole CM 11 thing for the NST. I keep asking myself exactly what it is I would like to do with my NST that I can't do now with the apps I have. Maybe my horizon is too low, but once I had the audio up and working I had far surpassed anything I thought would ever be possible, so I'm content.
There
are apps in the PlayStore which still run on the NSTG, but maybe you didn't install GApps and the Market. I've found some of my apps by Googling and adding "android 2.1" or "eclair" to the search string. You do have to be a little careful to make sure you're not getting trash (or worse).
Most of the apps worth having are text/reading based since the display is really not designed for animations or quick touches. There have been a number of threads in the forum where people have posted packages of apps that they have found reliable. I did that myself in
one thread awhile back and I keep my post updated. That's another possibility.
Or, you can just ask in the App subsection of the forum (as I have done before) if anyone has found "x" and see if you get a response.
