WordPress Plugin Customisations / Development

Hi There, I have a wordpress plugin that has had some small modifications performed to it. The plugin being used is called "Show Time" and is designed to display a radio station timetable on a wordpress website. The plugin includes an admin area where you can add dj shows. This is working perfectly. At the moment the plugin only shows weekly / daily shows. But there are some variations too which include: 1) Fortnightly shows 2) One off Shows 3) Monthly Shows 4) Weekly Shows The problem we are facing is that there are some djs who do weekly shows, then others who are maybe doing monthly (This maybe 4 weeks or 5 weeks depending on the days in the month) or fortnightly shows. So this needs to be taken into consideration. I require some additional changes which include the following: 1) I need the ability to highlight whether the show is one of the above, i.e. weekly, monthly etc. 2) Currently the schedule is showing the first show at midnight for that day, it needs to start from 7am. 3) Ideally list the main schedule page within a tab layout. e.g. "Monday", "Tuesday" etc. The current day to open first. The functionality Google Calendar is using would be ideal. Regards Tom
