A lot of tools have to define input/output folders. The Batch Convert tool is one example.
It would be good to add the Last Directory/File tabs to any navigation tool that involves saving. Missing in the Batch Convert tool.
A lot of tasks require moving from the same 'recent' folders using different tools. Eg moving to Batch Process after Batch Convert the user loses, is not offered the last folder path... and has to start again.
