how can i change the default editor in vanilla 2.1 to the one which is used here which gives option to upload images etc, i have attached image too.
you would need to sign up for vanilla hosting - since it is proprietary editor at this time.
I may not provide the completed solution you might desire, but I do try to provide honest suggestions to help you solve your issue.
is there any plugin for it?
what is that you want to do?
there is nothing that replicates that exactly. although lincoln said a new editor might be available at sometime in the future.
there is a list of fileupload programs and image uploaders that work with vanilla 2.1 in
you can also add to the list any plugin you use or tried (don't worry about duplicating answers) - many people are asked to do it - few take a minute of their time to do it, to help the community.
@Chalipa It'll be in Vanilla 2.3 (the next version). There's no announced timeframe for it yet.
