2018-02-18 Jim W Off to a good start but needs work. * Data is lost if you click on the browser window. The calculator closes and it's gone. * The calculator doesn't get focus immediately. One needs to click on the calculator window * It would be useful if clicks on the digits or functions were executed. One must use the keyboard. * Copy / paste should be implemented. Thank you!
2017-11-27 Firefox user 13483392 I miss the Mouseless RPN calculator on Firefox, so this is a welcome addition to my browser. The keyboard shortcuts are different, so will have to learn those. I do have some requests for the developer: - Improve the number display, perhaps larger numbers with an easy to read font. - Make all controls keyboard shortcuts. - Allow user to set number format. - Add financial calculations like time value of money and so forth. - Make shortcuts identical to the Mouseless RPN calculator.
2017-11-17 Firefox user 13475781 Crappy would be a generous description of this useless extension
2017-10-14 JernhardStang LAME. TOO BAD NO STARS IS NOT AN OPTION. NUMBERS FUZZY, SOME OPERATIONS OBSCURE, NO CALCULATOR "LOOK AND FEEL." IT MAY DO WHAT IT SAYS, IF ONE READS THE FINE PRINT AND LEARNS THE KEYBOARD OPERATORS. I'D PREFER WORKING THROUGH A "CALCULATOR" GUI, AND, WELL, REALLY, ONLY AN HP VOYAGER SERIES DOES IT FOR ME. I'M DUMPING THIS. AND I MAY DUMP THE FIREFOX UPDATE FOR AN OLDER VERSION TO GET THE HP11C-ish ADD-ON FUNCTIONALITY BACK. HI HI. JS.
