The Agent sidebar is here. Ctrl+E opens it on the right of the window, and your Copper Cloud decides what fills it: an addon, a small web app that updates without a new Copper. When the cloud hands out a new addon or version, Settings › Updates says Update available and Install loads it at once.

Big canvases are fast now. A board with hundreds of notes and images and dozens of live web frames draws only what is on screen, plus half a screen around it. Live frames load only when they are on screen and big enough to read, a few at a time; a frame that is let go shows a snapshot of its site under its title bar, so the board still reads as the real sites. Images drawn small use a small copy, and notes and text far zoomed out draw as simple blocks. Agents read a big canvas a page at a time: canvas_read takes overview, frame, region, ids, types, query, limit and cursor, and canvas tools no longer fail on a canvas tab that is asleep, just restored or slow to load. Ctrl+T lists Open Tabs, then History, then Search, and Tab and Shift+Tab jump between the sections. Closing a Saved tab keeps it in Saved, as in Arc; only the row's close button removes it. You can also drag a tab into Saved.
