There should be an option for inserting multiple images at once. Sometimes I upload lots of images for a post and want to write comments between them after inserting. Gallery feature is not suitable for inserting comments, media etc between images. In order to insert the images via media manager, I must enter the media manager many times! Media manager itself is not so fast so it takes a very long time. There should be an option in media manager for choosing and inserting multiple images at once.
There are two related future requests in the codex
