The web browser block of flash can (for now) be changed. With Edge for example go to "settings", "cookies and site permissions", "Adobe Flash", then change the setting from off to "ask before running". I do not know what will happen after December.
1) The Teaching Table host is often a Kibitzer. As a Kibitzer the Undo Button is not available to the teacher. The Undo Button is necessary for the teacher. Please add it ASAP. 2) Players and Kibitzers at a teaching table often want to save hands. A feature in the flash version allows saving all the hand results with one request to a folder. In v3 software, hands can be saved one at a time. The process is not easy and as far as I can tell the teaching table hands do not end up in personal history for players or kibitzers unless manually saved before the table is closed. Can the "save all hands" option be added?
Since you are promoting the Create Bridge Movies feature of the Web Version, please add the ability to import as well as export hands or sets of hands from Lin files and to Lin files on the user's Hard Drive, not just in the users' online hand history area. This is particularly helpful and meaningful to those of us who teach and run teaching tables.
