Sugar has introduced the concept of "Pinned Modules" in this release that consists of 4 (four) modules always available to users.
The decision to around this number was based on our research with our users that showed users use commonly around 4 (four) modules in their day-by-day operations.
However, Sugar understands that situations may require customizations to adapt to whatever comes your way.
Sugar Configuration
A new Sugar Configuration has been introduced to override this number called maxPinnedModules
You should be able to override it by editing your config_override.php:
$sugar_config['maxPinnedModules'] = 6;
Note: Be very careful not to defeat the purpose of this feature and pin "non-essential modules" to the list.
Resulting UI Experience:
In the following example, we have increased the number of modules to 6 (six).
Notice that, an extra element is appended if the module is not part of that list, therefore, increasing it to 7.
Note: Always account for an extra element in the list
