A gallery showing what you can do with Map Composer would be very
helpful.  Many users (like me) would often discover a new
functionality if there are examples (which is why linifiniti blog is
what I usually visit).

quite powerful and maybe the people just aren't aware about some
functionality.


After putting a certain amount of objects in a project, print composer would lockup. I don't recall exactly how many objects were in the project before it ceased to function but I ended up with about 45,000 objects in the .svg file. Specifically, when it came time to print or to export to file, it would lock up, crash really, with error message. The other thing was the way it handles polylines. I was trying to make highway polylines render correctly but there was a difference between what was seen on screen and what was actually printed. The polyline widths on screen were scaled too large compared to what I was actually trying to do. When printed I noticed they printed correctly. Getting the endpoints and intersections of two polylines to merge correctly didn't work either. I was trying to represent complex interchanges at the intersection of two highways with on-ramps etc. Couldn't do it. Polyline patterns are clumsy and difficult to set to useful patterns. Setting a scale is difficult. Maybe a wizard would help setting scale. Labeling is an issue. With tens of thousands of objects producing a clearly labeled print becomes a problem. It was tough even in Inkscape. Sometimes labels had to broken down into objects and each letter manipulated manually to make them appear in a readable fashion. I never really did figure out the labeling to my satisfaction but in the end just went with what I had, compromising just to get something out the door. The biggest problem though was print composer locking up while printing after I had all my coverages turned on. Perhaps a memory issue? I had 4gb of ram, not enough? I have bigger projects in mind and I'm not sure even Inkscape will be able to handle what I want to do.
