Currently there is no way to distinguish between breakpoints which stop no threads, one thread, or all threads. It'd be nice if new glyphs could be added to indicate at least the special case of tracepoints (breakpoints which do not stop any threads). I propose the glyph be the same square/corner shape as a regular/conditional breakpoint, but be colored green (go) instead of red (stop).
Using just a color as differentiator is not compliant with usability rules as color-blind people wouldn't recognize it. There must be some small widget added to the breakpoint icon.
The "Implements" and "Has Implementations" glyphs are distinguished only by color. Both are related to the same concept, with color used to show a particular detail. Another option is a vertical flip of the "Method Breakpoint" glyph, a shape similar to what I've seen for the same feature in other IDEs.
