I have a few custom 'Sources' in the catalog. In some sources I need to exclude some types of files and in other sources I need to exclude other types (and they might need to include types that are excluded in the other source). E..g, in the folders where the LaTeX files live, I don't want to see .xml files (byproduct of the make process), but I want to see .XML files in other folders.
However, it seems that the 'Exclude types' lists is common to all sources? If I add an exclusion in one source, it also appears in all other sources.
The UI suggests that you can have exclusions per source, just like you can have a depth per source.
So whatever it is, there an issue here. Or the UI is not OK, or there's a bug in the per-source exclusions...
