    Pretty good software - a little clunky, but the online YouTube Tutorial videos help out a lot. Very flexible, works well with Ubuntu 16.04.1 LTS. Also available in the Ubuntu Software Store.

    Thanks for the software, It also doesn't allow me to choose a scanner if I have multiple sources. Takes a while to set the scanner device, but shows some promise. However I can't get it to set up my Card Scan 800c which works with Sane

    :) Thanx for the software. I use croatian language, Ubuntu 14.04 (Linux). Instead "-", it writes me "—". I would like to disable sound. When I want to select part or whole text, I do not see any changes (different background) and this is confuseing. And the bottom line is very annoing - it is red and always goes left-right. Stop it, please! ;) That are my suggestions. Thank you.

    Using Ubuntu 14.04 (Linux) The program has nice features and has the potential to be a great program. The voice function is nearly uninteligible and sounds like the voice has a bad cold. I have been unable to save to file. The instructions need to be expanded rather than just list what the program can do. A user's forum would be helpful.
