Describe the feature request

Bottom is by far my favorite resource-monitor, but I'm missing a way to check a processes' priority.

I'm using ananicy-cpp to automatically manage process priorities and occasionally have the need to check in, and check if things are going as intended, especially while writing new rules
Which then forces me to use Htop

...

So it would be super awesome to be able to see a processes' priority in btm preferably as its own column just after the name and before the CPU utilization.
On Linux, this would be the nice value — I'm sure people on other Os'es would also benefit from being able to check on a processes' priority and potentially change it, if that's something we are keen on implementing.
