SDLXLIFF Toolkit issues

Dear Studio 2015 users,

I notice some issues when I used the Toolkit app (which I updated to the 2015 version) this morning:

1. When selecting a project folder or sdlxliff files for the Toolkit, Toolkit always takes me to the project folder under Studio 2011, despite the fact the my last accessed folder was the project folder under Studio 2015.  How do I change the default path to Studio 2015?

2. How do I add multiple sdlxliff files to the Browse for SLDXLIFFs... area, when they are in different folders?  I tried to add multiple files to the workarea, but the second one would always replace the first file.  (My client set up a project with several subfolders in the target folder to store each sdlxliff file.)

Thank you.
