Catgories filter syntax - do not show '~' parts in categories

[nathaneltitane]

Category name: Rim
Category Filter: ^%Wheel Rim & !(%= | %_ | ^Pattern | ^Sticker)

­'~' parts are showing at end of category

How do I prevent parts starting with special characters in general from appearing in custom categories?

@app4soft any related issue or trick to help? Thanks

Its probably somehow related to how LeoCAD handles "Helpers"/"Third Party" parts, which has | symbol in the title:

• Helpers and Third Party parts are not shown in the "Parts" list #941 (comment)

1. Parts with ~_=| prefixes are shown in "All Parts" list;
2. But, parts with | in the prefixes are not shown in appropriate categories, even such parts has !CATEGORY command defined.
3. If create a new category with matching keywords, parts with | in the prefixes appears in a such new category;
4. All parts with | in the prefixes are recognized as "Decorated Parts", even there are parts not decorated at all.

I'm not sure its possible to hide parts with ~ symbol in the title (if only not just manually edit all the categories in "Properties > Categories")

@leozide, I propose to add 4 extra checkboxes in "Properties > Categories" to show/hide parts with special prefix symbols:

• Show parts with special prefixes
  • [*] ~ (Subparts)
  • [*] = (Aliases)
  • [*] | (Helpers and Third Party parts)
  • [ ] _ (Physical colour parts) — this should be turned off by default.

This would solve both, this and #941 issues.
