Can I suggest features from abondoned plugins.

while searching through wordpress plugin directory, I frequently found many plugin which had not been updated for a long time or plugin author informed that they are not going to update plugin in future, probably due to change in their priorities.

Some of those plugin offered very good features in past but now not usable now due to ongoing changes in wordpress versions.

can I suggest such plugins for further development here?

one such example is http://wordpress.org/extend/plugins/more-from-google/ which provide combined search from wordpress and from google.
