The addition of a default column to the pages was another bad idea that Boonex had for the 7.2/7.3 releases. When a module installs, it places the blocks into the columns; usually main blocks in column 1 and blocks such as info, actions, etc into column 2. When it comes time to upgrade from a 7.1 release this additional column can made upgrading the modules a lot more difficult. Modzzz, in his usual fashion, went the extra distance and provided upgrade scripts to take care of any changes needed in the database. Thank you Modzzz. However, not all developers provide such scripts. Uninstalling the module is not an option; one loses the data of their members and that would be asking for all hell to break loose.
If Boonex had stopped and ask the community about this addition, and if it would cause any problems, then the developers could have said, "Hell yea it is going to cause problems." The addition added such little value to Dolphin that the value in no way approached the costs. Thanks a lot for nothing Boonex.
