Custom Work for Wordpress plugins

I have a wordpress website with a front end dashboard for my users (Basically a wordpress page with shortcodes and tabs) I want to customise and add features to a couple of plugins. (Eventon & Buddypress) and then have these displayed on the dashboard. I have 4 tabs on the dashboard: Tab 1 -> Explore Tab 2 -> Past Events Tab 3 -> My Social Life and Tab 4 -> My Connections Tab 2 -> Past Events (This lists all the Eventon past events) I would like this to be displayed in a grid format with a checkbox for attended (yes) and an photo icon 1) For every event that has finished I want the users to be able to click the attended(yes) to say they have attended the event, the event is then auto added to Tab 3 2) After the user has clicked on the attended event, they then have an option to upload photos they took at the event, this is added to a gallery of pictures, so everyone can see all the photos uploaded by people who attended the event. 3) Any pictures the user has uploaded should also automatically added to their own buddypress rtmedia album 4) Eventon has an RSVP feature, if a user clicks to say they are attending an event, this should also be added to Tab 3 (My Social Life) Tab 3 (Mysocial Life) 1) This should have all the events a user has attended and an photo icon the user can click on to see all the pictures from the gallery and also make any comments (like a discussion) 2) This should have all the events a user has RSVP'd to and also an invite button to invite other members to attend That should be it for now
