Hello,

When there are multiple terminal buffers, it's hard to distinguish them from their "buffer names" alone (which are pretty much the same, except for their PID). In this scenario, we have to resort to looking at the preview to know which one to pick:

My proposal is appending the term_title to all terminal buffers (see :h b:term_title), to make the distinction more clear without relying on the preview
