[ENHANCEMENT] More filter types in File Open dialog
Right now there is one filter and this includes all file types Imerge can open.
This is fine but I suggest you have additional more selective filter options. For example
.imerge files solo
Camera raw files grouped and/or a filter for each separate manufacturer raw file(s).
Pixel image files grouped.
Any other groupings you think might be useful.
note: .imerge is listed twice in the current filter.
Also, when you have multiple filters, the selected filter should probably/maybe be sticky. Certainly sticky for a given runtime, and maybe sticky across invocations. Maybe multiple stickies by context.
