Following a user request, I added a new connection control in all my tools, which allows to save and load connections configuration from/to a configuration file. This file is used by all the tools.
Here is the connection control
The password request form (as passwords are not stored in the configuration file)
And actually, the form which allows to select one of the existing connections configuration. It is used when an action requires an active connection to a CRM Server.
In order to help you to download all updated tools, I created an archive containing all tools.
