DocFetcher Pro 1.9 has just been released. There’s good news for people working with plain text files in general, and source code in particular: DocFetcher Pro now shows line numbers when displaying plain text files in the preview pane. This feature was ported from a code contribution to the upcoming DocFetcher 1.1.23 release.
In addition to the new line numbers feature, an indexing crash was fixed, and a small index optimization step that is run after each index update was added. For details, see the changelog.
