Enhance the "select from..." context menu option on views to (as it does for tables) allow updating via the grid.
Not expected to work for all views, of course. (Is there a way to ask firebird which views are updateable, either naturally or because of a trigger, other than just attempting it? Only one relation dependency OR a trigger is defined? But if a view depends on another view, which depends on a table, and it's still naturally updatable, what would the dependencies show?)
