Thank you all for your great efforts.
Not at all sure if this is the correct place to post a Webtop wish list as the last post was April 2018.
Please let me know if there is a better place to post and any feedback.
Some suggestions -
Calendar - Auto refresh page.
Contacts - Search any field in contacts - At the moment phone numbers can not be searched.
Calendar - Links to this calendar - A solution like Sogo which has public and authenticated user links for CalDAV URL, WebDAV ICS URL and WebDAV XML URL .
Calendar - Search results - Show all results if search field left blank on search request with a date range selector or add an Agenda view with a date range selector.
Emails - Convert an Email to an Event.
Emails - Convert an Email to a Task.
Emails - Email delegation.
Emails - Manual check new emails now button.
Emails - Forwarding of emails to external email address (internal addresses work).
Emails - Allow external imap accounts.
Emails - Option to auto add unknown contacts to address book when replying to unknown email address.
Emails - Digital signed email option.
