Hi,
I've noticed that "Edit --> Format --> Reflow Lines/Block" only seems to work if the Pref for "Editor tab : Display tab : Long line marker" is enabled.
It would seem to me that reflow should work as long as the Columns combo box contains a usable value (since it doesn't get grayed out when the "Long line marker" checkbox is unchecked).
If the current behavior is what's desired, then when "Long line marker" is disabled, perhaps it would be useful if -- when the user tries to reflow -- a message appeared in the Messages pane at the bottom indicating that it won't work unless Long line marker is enabled.
Sidenote: I notice that a max column value shows up in 2 separate places in the Prefs: "Editor tab : Features tab", and also "Editor tab : Display tab". The one in the Display tab affects reflow behavior.
Thanks, ---John
