A browser-based resource usage view of per-tab CPU/RAM etc.

This really should be top priority in my opinion.

Here is example that just happened to me:
I opened a website https://msty.app/pricing and left it running in the background as I navigated away to different tabs/pages. This hidden tab was actually excessively consuming CPU. If I had a task manager, I could easily see which tab misbehaved, and in activity monitor I could not see which tab it was, because it was shown as "Orion Web Content". Luckily I could decude from the "CPU time" that I had opened it 2 hours prior and I didn't open too many tabs in that time.

Even better would be ability to actively see this excessive CPU usage, on the tab itself. For example, if Orion detects that an inactive tab is consuming excessive amount of CPU (for example more than 50% of one core), it could color the tab in red or show a power icon next to it (). This should not show up for the active tab, as its usage would normally be higher due to user's page interaction.

If I didn't have a CPU usage indicator in the menu bar, I would never have known something was misbehaving.

frin I wouldn't even mind an indicator on the active/foreground tab if it is consuming CPU, etc while I am not interacting with it (i.e. not clicking or typing within it). That indicates to me it will likely be a resource hog if I don't close it before switching to another tab.

Chrome/Chromium has a "task manager" that allows you to see the memory/CPU usage of tabs and terminate resource hogs:

Right now, the only way to do that in Orion is to use Activity Monitor, where I guess I get to see the domains, but I have no idea which, say, YouTube video, or google doc, is which:

Orion has a habit of somehow eating my RAM even worse than Chrome does, and I don't always want to use the nuclear option of suspending all tabs. I'd like to know which tab even is the culprit and only then make the decision of if I'd like to suspend it or what else to do about it.
