Request: Self-contained / portable Sublime Merge on macOS

[htien]

Problem description

On macOS, Sublime Merge is only available as a standard .app bundle and always stores its data in global system locations (e.g. ~/Library/*).
This makes it difficult to use Sublime Merge in portable or isolated setups, such as running from an external drive or keeping multiple self-contained environments.

Preferred solution

Add support for a portable mode on macOS, where Sublime Merge can run from a user-defined directory and store all configuration, cache, and state locally (e.g. a Data/ folder).
This could be enabled via a flag (e.g. --portable), directory detection, or an official portable .zip distribution.

Alternatives

Document an official way to redirect all Sublime Merge data paths to a custom location, or clarify macOS limitations if portable mode is not feasible.
