I would like to request a new feature, which I think many of the plugin users would benefit from, if not already available:
In a list we could set up a device or devices and a client and set a maintenance reminder e-mail, so that on a particular day the system would send out a Maintenance Reminder for the Client to remind for i.e. annual maintenance, cleaning, update installation, etc. of a particula device and so the Client would be reminded to bring his/her device(s) back to the repair store to do the annual maintenance on the device(s). The Client could get an e-mail in which the Client could Accept or Deny the Maintenance and if accepted a new Job would be generated for the Client and Device(s) and so the Repair Store could plan with the job, inform the Client about any new Service prices, etc. so the work would be generated by the Clients as well.
Thank you in advance,
PS: I already started to translate your plugin on Wordpress Translations website, so as soon as I will be finised, I will let you know and will ask you to put the translation into the plugin.
