Wordpress Plugin Development

I'm interested in creating a WP Plugin, similar to [login to view URL] I want to make some improvement though: - currently the plugin has a Flash based Title Editor with some templates, this exports the titles as .png but I want to export it as text so one can copy it. Or if there's a similar editor that works directly in java or html will work, I don't necessarily want it in flash but I do want something similar with the current one; - add some more fonts and templates to he titles editor; (and show me how to add more in the future) - I want to be able tore-size images because now you can't; - to be easy to edit the background image directly from the plugin, without going to style sheet; - activation with paypal e-mail address. Please keep in mind that this is not a free plugin and I don't want it to link back to the original one because I want to sell it. I have this plugin installed on my website [login to view URL] user: test password: test123456 go and check all the plugin features and tell me if you can do what I'm asking. Thanks!
