Hi vnex mall,
There is a marketplace
section where you can find some controls/modules for free ( some are paid). If you can elaborate some more about what you are looking for I can provide you some guidance in case you want to develop such control/module instead of buying it.

Do you want to have your say when we set our development plans?
Do you want to know when a feature you care about is added or when a bug fixed?
