+Subject: [PATCH] Add comma separated filtering to ApplicationsTableView
+
+Instead of using ProcessSortFilterModel we can implement in
+the callback of the KSortFilterProxyModel.

+Subject: [PATCH] ApplicationsTable: Remove unneeded ProcessSortFilterModel
+
+ProcessSortFilterModel handles filtering pids and to which user a process
+belongs over a normal QSortFilterProxyModel. In doing so it also
+sets the filterKeyColumn to nameColumn in findColumns(). Note that the name
+of the name columns of the process and application table is different
+("name" and "appName"), so the filterKeyColumn is also set by ApplicationTableView.
+However this is racey depending on when the binding is evaluated.
+Since we don't need the extra features of the ProcessSortFilterModel we can use
+the existing SortFilterProxyModel in charge of filtering columns (something that
+the ProcessSortFilterModel also did) to also handle the row filtering.
+BUG:445544
