Sitefinity VSS management should not be different than any other ASP.Net web site project. Toolbox information is stored in configuration files. You should treat configuration files as you would web.cofig
. In this case you should checkout ToolboxesConfig.config
file make the change and then checkin. So next time other developers get the latest version will have the same control in toolbox of their local Sitefinity version. Merging the data could be done with a database schema comparison and replication tools.
