Is the problem with split transactions and the "other" categorizations a known issue?
When I enter a transaction and choose a top-level expense category (not a sub-category), the transaction gets assigned "Category:Other." However, if I enter a split transaction and choose the top-level category for a portion of the expense, it doesn't go into the Other area, it stays attached (in reports, e.g.) to the top-level Category and is separate from the "Other" amounts. There seems no way to fix this.
