As for software ideas, I think that your ideas are really good.
However, I think some users won't want to have the info outside of the viewable area. One thing I think that could be useful is to have this info on the main viewable area (as an option) but only when a certain key combo is pressed. We have some data like this for our fbcp (https://github.com/TheFlav/rpi-fbcp) driver, but the https://github.com/juj/fbcp-ili9341/ driver is better in general once it's a bit more stable all around. Our fbcp driver has a low-batt indicator that pops up, but since it's built in to the fbcp, then it's hard to augment.
I think it's also possible that more people will start doing builds that use the entire LCD (by opening up the shell area). That's where I think it'll be good to have this data easily placable anywhere based on a parameter.
