Horses for courses. On a simple model it is easier to have the tabs connected, and in small parts it may be difficult to attach a seperate tab accurately. On the other hand, these tabs then make one section sit higher than the other which looks less good and can cause fit issues. In other situations there might not be room in a small corner to put a worthwhile tab.
- Take into account the effect folding a tab will have on a corner edge, especially a valley fold. It might cause an inadvertant seam line or bulge where the paper is bent.

- If the paper walls are thick enough then tabs aren't needed. Same goes for very small structures where one piece can happily be glued to the edge of another.
- Tabs can cause issues with unevenness or just being visible if a model has any kind of interior or interal space.
- Avoid using tabs to connect joins which are essential to place accurately for a good fit in the overall model. Right now I am making some designs which use tabs in a different way; tab-and-slot frames which often don't even require gluing, but guarentee a good straight and strong structure.
