Need some feedback on this Twitter tool in development

I’ve developed a pretty simple Twitter scheduling tool that can allow you to easily set up an automated schedule and cycle for your tweets. Would love to get some feedback from some Twitter users on what sort of functions and features might be worth adding prior to making it available.

The feature list at the moment is as follows:

• Log in using your existing Twitter credentials (no additional registration necessary)
• Create a new tweet to be tweeted at any given future date/time
• Tweets can be one time posts or added to the daily tweet schedule
• Set any new/old tweet to be tweeted daily
• New tweets can be instantly tweeted in addition to being scheduled
• Easily remove a tweet from being cycled
• Edit a saved tweet
• Save & Schedule a tweet from a list of your recent tweets
• Set the time interval for your tweets to be automatically posted

Here’s how it’s looking thus far:

This Twitter scheduling tool will be available for use soon. If you’ve got any good ideas, or can think of anything that you would find useful in a Twitter tool, please comment below and I might just add it in before launching :)
