Hierarchies 😩... One of the biggest recurring time-consuming issues I sometimes encounter is making decisions about _where_ to put some (new or exisiting) code/feature, i.e. in which package, new or existing, considering: functional fit (topic), structural fit (pre-existing data format conventions with the rest of a package), and if possible, not introducing new dependencies as a result of new feature... Sometimes these three aspects are mutually blocking each other and it's so time cons…
