Restrict, do not swipe Brandon Miniman makes the case that clearing the recents list forces a cold start that spikes the processor to nearly 100 percent, where waking an app from hibernation spikes it to about 50 percent, so on a modern phone, which he says should carry at least 8GB of RAM, he leaves apps alone and instead opens Settings, then Apps, then the offender, then Battery (Restricted on Samsung Galaxy phones), and turns off background usage for that one app; he warns plainly that a restricted app may misbehave or drop notifications, and he still swipes away anything frozen or glitching.

One folder, no database Anurag Singh left Notion for ordinary .md files in a regular folder, with subfolders only where he wants them, edited in VSCode or an alternative like Cursor, Antigravity, Zed, or Neovim, then installed Syncthing on each device, paired them by device ID, and shared that one folder so a change on one machine lands on the others; he is candid about the limits, since Syncthing synchronizes rather than backs up, a deletion travels to every device, and editing the same file on two devices that are out of contact leaves you with a conflict copy.
