- search was not searching in id, phone/email, location
- setting status or percent&date completed was not working for the responsible under some conditions
- for the conversation of days to hours always 8h were used, now that's the default if nothing is configured in the PM
enhancements - some might call bug-fixes too ;-):
- configuration of the rights of the responsible:
a) implicit edit rights (default is only read)
b) additional fields to edit without edit rights: eg. description, used time, ...
- user preference to show status and percent again as one merged icon (default) or as two spearate ones
- user preference to show a numeric Id, can be used eg. as ticket number
