<div dir="ltr"><div>I think you're right, those notifications are unnecessarily noisy.

<br>
I've been meaning to bring this up for a while, but hesitated because<br>
it's somewhat a bike-shedding issue. I'll throw it out there, though,<br>
as a small thing that I think detracts (and distracts) from the user<br>
interface of the notebook.<br>
<br>
Right now, it seems that when the kernel starts executing, the words<br>
"Kernel Busy" flash up in the upper right of the notebook, and when the<br>
kernel stops, "Kernel Idle" flashes up there. In cases where you have<br>
lots of computations being sent back and forth (for example, when<br>
playing with the new interactive widgets), this activity in the<br>
interface in the corner of my viewing angle gets rather distracting. It<br>
even gets distracting (for me) when executing normal computations---I<br>
see a flicker of something when a result is returned, and automatically<br>
glance towards the flicker and see it is just the kernel idle message<br>
flashing up. This needless distraction breaks concentration and<br>
detracts from the content that just appeared.<br>
<br>
Proposal 1: eliminate the kernel busy/idle indicators from the main<br>
interface. We already have the indicator in the input prompts when<br>
executing normal cells (e.g., [*] instead of [number]). We could put<br>
some indicator of kernel status in the menu if it seemed necessary.<br>
<br>
Proposal 2: Make the kernel busy/idle status indicators much less<br>
distracting by making it a small muted icon or filled circle, similar to<br>
a hard drive or ethernet port activity light, that only is displayed<br>
when the kernel is busy, but turned off when the kernel is idle.<br>
<br>
Thanks,<br>
<br>
