The way that the main overview page limits the number of transactions displayed (currently 5) is not an appropriate use of Qt. If it's run with a DEBUG build of Qt, it'll result in a segfault in certain relatively common situations. Instead of artificially limiting the rowCount() in the subclassed proxy filter, we hide/unhide the rows in the displaying QListView upon any changes in the sorted proxy filter.
