Hello , Im doing a project about krita . I just wanna ask about the limits that developer have .Maybe some things arent available for them or they have issues about the hardware , databases ,protocols or security.

Um... You really need to be much better prepared: make sure you

* first properly explain about this project. What is it, what is it for, why are you doing this. Introduce yourself.
* then find the right place to ask developer's questions. This is more of a user support forum
* then figure out the easy things for yourself, for instance by reading the contributors pages of the manual
* then come up with some specific questions that show you've done your homework
* and make sure you write acceptable English. It doesn't have to be perfect or at a native level, but it shouldn't be this slangy.
