Windows doesn't have a programmable equivalent does it? Last time I messed around with this stuff I got by with an Electron app and using browser desktop notifications but I think I couldn't actually modify the taskbar/put icons somewhere.
Unclear what you mean by programmable, but https://learn.microsoft.com/en-us/sysinternals/downloads/pro... is the bee's knees and you can set an option to have it take over taskmon.exe, launch on login, and put as many of the widgets in the taskbar as you fancy. I love it
I use XMeters. It's okay. You have a little customization to which meters to display, but it does pretty much everything I'd like it to. Per-core bar graph, memory utilization, and disk and network up/down rates.
The config ui is unbelievably slow with a very early windows 7 aesthetic. But I've seen that screen maybe three times in as many years. It's fine, I guess.
The main.taskbar widget seems perfectly cromulent though. No noticeable impact on system resources, and the updating feels plenty snappy. I'm happy with paying a few bucks for this widget.
Electron is overkill, but it can be quite lightweight with something like Tauri as it doesn't bundle another browser and uses the default web renderer.
