Sure thing, you need to do two things to achieve this:

1. Enable blank searches in your community

2. enable search export via csv

Your need to raise a support case for number one, two i think you can do via admin then you simple run a blank search on your community then filter by just ideas then using the menu export search results to csv.

This export will include all the meta data associated with each idea making it easy to filter and report from the export. 

Yeah you're right to want it and is normally default our the box:

Initially i thought you had something custom but on reflection, it looks like the Mondrian layout which i use myself so i checked my own community and it does the same as you in that the main page doesn't show which topics have been kudos by yourself.  I'm using the out the box layout so i suspect this is a bug or feature of this layout but maybe someone can help advise how to make it work as you want.
