Should state clearly that doesn't work with TypeScript files

After purchasing, found that it doesn't actually support TypeScript files even though the description says otherwise. Only after visiting author's website do you see this listed as a known issue.

The inability to work with .ts files is not the author's fault--it appears to be a macOS limitation.

That said, the App Store description should be updated to display this known issue.
