We are continuing to test this product and finding it's working well for us so far
Here are some suggestions:
Organise terminals automatically by subnet (i.e. some kind of tree view). It would be fine for the admin to have to manually enter the subnets (like in AD Sites & Services). Terminals not having a matching IP could go in a 'default' section.
Apply templates at the subnet level, so that new terminals automatically pick up those settings without stalling at the "I need a configuration" screen.
RPi config.txt settings built-in to manager (browser works OK of course, just another step).
Ability to reboot all terminals in a subnet, for example for new version, with some staggered approach like one terminal per minute (TFTP might be remote and bandwidth limited).
Terminal list in wtware Centre should show status of each terminal in the list (online or offline). Eg the workstation type icon (PC/RPi) could be greyed-out as it is now for offline or coloured when terminal is online, discovered by ping or such every minute of so perhaps.
wtware Centre can be locked by another administrator. As well as waiting, we should be able to forcibly take over the session.
