Now, filtered segments are displayed with their context (previous and next segments). That's perfect.
To make this feature more perfect, I'd like to request an additional option to jump to the next/previous filtered segment (in particular, one with a bookmark and/or note), without doing the filtering operation.
The only reason is: the "context" is sometimes or often wider than those two adjoining segments. A wider perspective is what we need to improve the quality of our translations, I believe.
Sorry, I don't understand what AppleScript is.
So, let me renew my request: How about giving the user an option to choose the broadness of context (i.e., the number of adjoining segments) to be displayed on the Grid when a filtering action is done?
