Hi Mogens,
For the new clients (Synergy GUI and CLI, which are now the only supported clients in 7.2 onwards), I do not think there are any user or client-side preferences for work area preferences. The problem is that if you change the ccm.ini file in the Synergy server installation area, this affects all users. You also need to perform a ccmdb refresh to force the back end session manager to restart sessions in the pool of sessions it manages since the ccm.ini settings are only read at startup of the session and thereafter cached.
AFAIK, there are no client-side user settings that support controlling work area preferences such as wastebasket location. So there is no way that you, as a client user, can say "just for me, I want the wastebasket at this specified location". If you change the server-side setting, every user will have to have access to the same path on their local client machine, perhaps by mapping a network drive.
Over the years, Synergy default settings have become somewhat disorganized and inconsistent. They really need a review to decide what scope(s) make sense. For example, should a setting me installation wide for all databases, database wide for all users of that database, type-specific for a specified database, user client-side defined, or some combination thereof. In some cases, where we used to support a user client-side setting has been lost because the back-end session pool runs on the server as the Synergy administrator user. This is part of the functionality gap when the classic clients were retired at 7.2. There are other functionality gaps, such as no GUI support for certain operations like DCM, Save offline and delete, type definition, and migrate. Given the development bandwidth available, it was not possible to fill all these gaps in a 7.2 timeframe.
I suggest you submit an RFE to the Synergy RFE community at http://www.ibm.com/developerworks/rfe/. This allows other users to vote for the feature, and it may also get discussed in VoiCE sessions. This allows the product manager to prioritize where finite development bandwidth is used for new releases.
Best regards,
David.
