Is there available online a summary table, or better yet, a decision tree, that presents the conditional logic of the somewhat complicated laws of hesech hada'ath/shinui makom (diverted attention, e.g. by changing one's place), when one is required to make a new blessing over a food item or meal because the original blessing no longer applies?
For example, it should cover the consensus rulings regarding going outdoors vs. to a different room, for a bread meal, mezonos (non-bread grain), other foods, with and without leaving people behind. Ideally, it would include disputing views of major authorities, as well as other types of hesech hada'ath / hefsek (interruption) that would also require a new blessing.
