Resource Manager

Your operating system blames 1DevTool for every process a terminal starts. Task Manager nests the shells, `node` and `claude` under our row; Activity Monitor spreads the app across "Helper (Renderer)" rows and gives you no way to map one back to a tab. So the number you see is real and tells you nothing about which of your six panes to close. The Resource Manager names that split instead of hiding it: 1DevTool itself, the terminals you started (with the line “Programs you ran here — same RAM in any terminal”, because those processes cost the same in any terminal app), and everything else on the machine — three buckets that add up to what your OS reports. Expand one and every terminal is listed the way its tab is, with its own CPU and RSS. When a pane pins the CPU across two consecutive samples or starts flooding output, it gets an attention row naming the reason — “62% CPU”, “8.4 MB/s output · throttled” — with **Reveal** to bring that exact pane forward and a **⋯** menu carrying **Pause output**, **Lower priority**, **Hibernate** and **Close**. Underneath sit **RAM used**, **Available**, **Swap**, **CPU load** against your real core count, whether **WebGL** is on hardware, and a **Busiest other apps** list that names the browser eating 31% instead of letting you blame the workspace. **Recent stalls** shows any freeze in plain words, and **Copy diagnostic report** puts all of it on your clipboard as Markdown, ready to paste into a bug report. One footer button, **Improve performance**, sleeps inactive tabs, hibernates idle agents and clears buffers in a single step.
