Plugin v/s entity

Hi,
I have been working in librecad for a past few months and have already explored its basic working. I have tried some hands on plugin development and entity addition as well. I have come know that new entities and patterns can be added in it through these two approaches.
But I have a little query that which one is a better approach to achieve the goal, from user and developer point of view.
With which approach should I continue my contributions in it?

 

generic or specialized contribution?

if the contribution is for a specialty, ie only useful for a sector like survey or CNC the best is a plugin

if the contribution is generic, ie serve to improve LibreCAD for all sectors, then directly in LC souce code

look at the list of bugs or feature requests:
http://sourceforge.net/p/librecad/bugs/
http://sourceforge.net/p/librecad/feature-requests/

well your reply cleared my doubts for both the cases.
Thank you.

Yeah I have been going through these links. But what exactly you want to convey me through this?

One thing, 2.0 is in stabilization phase, so new features are for 2.1 (not forked yet).
