redundant columns in project list of PTBatcherGUI

[zarl]

Usually (i.e. using defaults in Hugins "stitch" dialog) both project file and output files are located in the same folder. If that's the case both columns "Project" and "Output prefix" in the project list of PTBatcherGUI display almost the same information: each shows the complete path to the project while "Project" shows the "pto" extension and "Output prefix" hides it.

A more concise presentation would rearrange order (first file, then path) and omit the path in the second column if both paths are identical, e.g. like this:
Project column: <project-name>.pto (in /path/to/my/project/in/progress/)
Output prefix column: <output-prefix>

If both paths differ then only the relative difference of the second path is shown, e.g. like this:
Project column: <project-name>.pto (in /path/to/my/project/in/progress/)
Output prefix column: <output-prefix> (in ../../stitched/)

Another approach would be to only show the path as 'help text' when hovering with the mouse over one of these columns.

Also, PTBatcherGUI doesn't remember column widths set by the user. Preset column width is absurd, i.e. too long for "ID" and too short for some other columns. An automatic approach to set the width according to the content would be nice to have. If the user sets the width this should be remembered by PTBatcherGUI.

Current behaviour is observed in recent versions of Hugin / PTBatcherGUI on Mac OS X using a 1600x1200 display, on smaller screens (e.g. laptops) this might be rather annoying.

Made the prefix display relative to the path of the project file in rev dfe005333233.

Concerning the column width: there is code to store and recall the column width. It is stored in the settings under BatchList\ColumnWidthx. This works here on windows. Could you check, if these items exists in the settings. Or maybe on wxMac the column width is handled different?
