It can get quite bothersome when designing an Arabic typeface and having to set the RTL flow in the edit view every time. Having an option to specify a default or at least remember the last used setting (or something more intelligent based on the Unicode Bidi class of the characters) would be awesome!
I try to fix this.
But for now, try to keep your tab alive longer. Don’t go to font view to get to new glyphs, either type them or use the cmd+F search dialog to add new glyphs.
I have fix that.
