First, **read and thoroughly understand** both:

 - [What topics can I ask about here? (Stack Apps)][1]  
  and
 - [What types of questions should I avoid asking? (Stack Apps)][2]

That said, **you *can* propose** changes to the API, or request apps, or request scripts.
Keep in mind that this site is not an app/script writing service and almost everyone here is a volunteer.

It would be better if you **ask for help solving a particular, Stack Exchange related *need*** that you think could be solved with an app or script.

A good app/script request:
==========================

 1. Has a clear, actionable description of the desired result. Pictures help.

 2. Clearly aims to improve the use of Stack Exchange sites and/or Stack Exchange data.

 3. Has broad appeal and/or looks to be something fun or interesting to program/answer.

 4. Avoids ["X Y problems"][3]. State your desired *result* in terms that don't depend on how you think it can be accomplished.  For specific programming questions, ask on [Stack Overflow][4].


Tag your request with one or more of:
=====================================
[tag:app-request], [tag:script-request], [tag:feature-request] and/or [tag:support], as appropriate.  
(Additional tags may apply as well. EG [tag:answers], etc.)
