During paste operations, we don't actually need autocomplete. It's important to keep the options in mind, but we can delay evaluation until they're actually used.
Change autocomplete related methods to return lazy IEnumerable objects instead of returning a pre-populated read-only list. Add a LazyList<T> class that can handle the once-time evaluation logic. If no element of the list is ever checked, then the auto-complete code never runs.
Change ViewPort's UpdateToolsFromSelection tha happens when the selection changes. Only evaluate it after the edit operation is complete.
Tuple autocomplete is weird, because it happens in stages. This is different compared to other things, where choosing autocomplete always finishes the cell.
* Don't crash if the tooltips try to get bit options that don't exist.
* Duplicating arrays should duplicate the format correctly.
* Updating a table name should update streams that care about that table.
The list of tables is getting crazy, and I keep adding more.
* Don't show tables in the table list if they're 'matched length' tables. Example, level-up moves. These are already accessible because the table tool uses matched-length tokens to show multiple tables in the tool at once, to make editing data easier.
* Split the tables between two lists: a header (containing up to two tokens) and a body (containing the rest). This should allow for progressive disclosure, to help make the list more manageable.
