We have just decided to increase the total number of apps and functions from 10 to 15. For the best user experience, we think 10 is the most suitable number, but there is many requests to increase it, so we do adjustment.
We can remove the limited of number but it might cause some performance issues. Please try 15 firstly, then we will consider to remove limited due to comment from customers.
The change will be applied in the next release in this week (latest Apr 14)
Please be informed.
