Hello,

Is your server in cloud or on premise? StandardERPServer-Slave is required to launch the web client.

Regarding your questions:

1. It does work in the latest released version, but it depends on where the server is located. I have tested with a local test server, and made sure it has StandardERPServer-Slave executable inside.
You can find more detailed manual here: http://www.hansamanuals.com/main/english/mailnumber___61141/theconf___563/manuals/levelzero___61127/version___85/hwconvindex.htm

2. Yes, there should be. If you cannot find something you are looking for, please report a bug (development might move it to a wish, if it was not intended to be included to a web client)

3. As far as I know, it is not fully responsive
4. To my knowledge, it is not the top priority currently on the development plan
5. Yes, it should work on all OS


Best regards,
