Bookmarklet
It is simply put a kind of browser extension and can be used in this case as a shortcut for creating new posts.
Have a look at a demo:
- create a new bookmark in you browser
- add this instead of an URL while changing the second line
var server = ...to your servers ip-address or domain
javascript: (function() {
var server = 'http://YouNeedToChangeThat.com';
var applicationUrl = server + '/c/0/p/create';
applicationUrl += '?url=' + encodeURIComponent(window.location);
applicationUrl += '&auto_close';
window.open(applicationUrl);
})();
