... and you know what? This made me buy the app!
Another suggestion: The "searchable text"-option should be performed on the original document (or such an option should be added). At the moment it just creates a new file with _OCR added in the document's name, which needs to be saved in addition to the original document. this destroys my workflow as my pdf files are managed by an app and if I do this, I need to reimport the newly created document (_OCR).
Furthermore I get vertical lines (in light grey) over the document when applying the "searchable text" option.
