Query regarding Plugin development

Does developing a plugin and publishing it count as a contribution.
What I mean is that it is advised to fix some bugs in the repo as a starting point, so can I develop plugins instead, will that be taken into consideration?
Sorry if this is not the right place to ask this doubt.

it does but it would make sense that you try to fix a bug as well as it tells us directly your coding style and skill level.
We won't tell you how to style your code in plug-in although we expect that is close to what in Joplin Core is done.
