Status in Hugin - Panorama Tools GUI: Triaged

Bug description:
The Problem: Small stitcher errors caused by nodal point errors, poor choice of control points, and/or motion can often be corrected in Photoshop using layers and masks if the exposure corrected, remapped source images are available. For "Normal" output, these are kept if the "Remapped images" option is enabled. However, for "Exposure  fusion:Fused and blended panorama", the "Remapped images" option only keeps the uncorrected remapped images, i.e., the input to the enfuse process. The corrected images (i.e., projectName_stack_ldr_N files ) are designated temporary and erased when the blending process is complete. This precludes fixing the seam errors in Photoshop.

WorkAround: The desired files are actually produced as part of the stitching process. Using a standalone copy of the Hugin_tools (I got mine from Harry van der Wolf's website), the project file can be run through a pt02mk and make all process to generate the desired files. (I created a scriptlet that you can drag and drop a project file on to automate this process.) Any unnecessary temporary files must then be removed manually. The disadvantages of the workaround are obvious: additional manual steps and downloading of the standalone tools which wouldn't otherwise be necessary.

Feature Request: Add support to the GUI stitcher tab so that the projectName_stack_ldr_N files are retained. Some possibilities:
a) Add additional "Exposure fusion" checkbox to retain exposure corrected, remapped images when "Fused and blended panorama" is selected. 
b) Extend semantics of current "Exposure fusion:Remapped images" checkbox to also save projectName_stack_ldr_N files when "Fused and blended panorama" is selected.
c) Use "Normal:Remapped Images" checkbox to enable saving of projectName_stack_ldr_N files when "Exposure  fusion:Fused and blended panorama" is selected. (This is my least favourite option due to potential user confusion and should probably only be done in the context of a redesign of the "Output" GUI.)
