OK so with 7 voters we can’t motivate a developer to produce plugins 
I would have thought there would be more need behind this, but probably everyone is happy using (meanwhile maybe outdated without notification) WP Plugins.
I am closing the poll and will use this, plus Plugin dev help needed for possible dedicated CP plugin - #10 by Pross, "Must Have" Plugins List and What are your top 5 plugin needs? - #24 by Daniel to compiles a list, that shows:
- plugins people seem to use/want most from top to bottom
- wether or not replacement exists
- oterhwise try to reach out to said plugin author and make them officially support CP (or mark it as "not suggested / incompatible)
Based on that I hope dev’s could then (proceed) picking what they want to develop, and users what they want to support, or snippets, or tutorials, whatever adequate.
The contact form plugin bespoken above has been submitted today to the repo (that one that provides remote updates).
As soon it went thru that, it will also be submitted to CP repo.
