If you have root and xposed you can change it to functional using xstan on something like that app sorry don't remember full name
Edit: Thanks /u/impact_ftw for reminding it :P Link
Hi thanks for the reply. Turns out Nice Lock is a launcher, but I won't be replacing Nova Launcher. I'm mainly looking for something like this https://play.google.com/store/apps/details?id=lfprodev.xposed.xstana
Sure thing. I'm using an option from Xstana to change the square and triangle.
The app drawer button actually also comes from Xposed GEL Settings (which I linked to another comment). I enabled options to hide the app dock (since my folders are on the left now), change the home screen grid to 6x4, and to hide the app drawer button. I then enabled options to change the Home (circle) icon to "Open App Drawer" when I'm on the homescreen. If I'm on any other screen or in an app it still looks like the home button and takes me to the homescreen, but I can still open my app drawer with fewer buttons on screen. It has a nice little animation too so it looks like it belongs. It works really well since you have to be on the desktop anyway to open the app drawer (unless you use a bunch of screens, which I don't).
You could also try this:

Here is what I used when I had CM13. https://play.google.com/store/apps/details?id=lfprodev.xposed.xstana
With the Xposed module, Xstana I believe that is the Nougat stock nav bar.
If you have xposed you can install something called Xstana to change it that way.
