I suggest to implement the following feature:
Creating an Add-in for Microsoft Excel. With this Add-in it should be possible for an Excel user to trigger a specified report (via the Report Server), which uses the data the user currently works with. Therefore a example of the Excel file probably has to be specified within the designer, but the user then can use his current Excel data as a source.
A typical use case might be:
The world runs on Excel. Unfortunately it is not made the make pixel perfect report prints (it was never intended to). However it is often used for making reports and other tasks which have to be printed out or save as an PDF in orer to hand it over to another person (for example calculations). A lot of people invest much time to improve Excel print-outs with the onboard tools. LL would be much nicer an could offer more possibilities.
