First session

1. Install Sublime Text 4, Build 4200, then use File, Open Folder on the project root so Goto Anything can index it.
2. Save a project once the folders look right. Switching projects restores tabs and unsaved buffers.
3. Keep overrides in Preferences, Settings, user overlay so an upgrade does not wipe them.
4. If you want packages, add Package Control from the Command Palette and keep only what you will use.

Common snags

wrap_lines ignores newer ruler values

Build 4200 taught wrap_lines to honor newer ruler settings. Update if an older copy still wraps the old way.

Find field stays short on multi-line queries

Build 4192 let the find field grow with multi-line searches.

CPU stays high after launch

Large trees are the usual cause. Exclude generated folders and do not open a drive root. GPU drawing should spend less power, but a bad driver can still be turned off from the Command Palette.

A shortcut does nothing

Open Preferences, Key Bindings and search for the command. The operating system may already own those keys.

Session did not come back

Hot exit writes unsaved buffers when the app closes. If the process was killed, open the project file again.

Habits that help

Keep generated output out of the indexed folder. Learn Goto Anything, the Command Palette, Ctrl+D and tab multi-select before you pile on packages. Read the capability page before you replace a built-in tool. Capabilities.

When a scanner quarantines the installer

1. Write down the exact path in the alert.
2. Compare its hash with the published digest once that digest exists.
3. If the hash matches, restore the file and add a narrow exclusion for that path only.
4. If the hash does not match, delete the file and fetch it again from this site.
5. Do not disable the scanner for the whole disk.
