Bugs and Feature Wish List for Tioga, Viewers and Ancillaries

            March 26, 1982

 Autoscrolling needs tuning; should use some CedarGraphics variant of blt to minimise screen updates. (Annoying; Graphics & TEditScrolling).

 Selection extension between multiple nodes is inefficient and causes the screen to flicker. (Annoying; TEdit: TEditSelection).

 When making a secondary selection, there is currently no feedback for the logical insertion point. (Annoying; TEdit: TEditSelection).

 Line tables are allocated on the basis of intial size for a text viewer and are not reallocated if the viewer size changes. (Annoying; TEdit: TEditDisplayImpl).

 Mouse tracking in Text is slow, especially on Dolphins. Character resolve algorithms could be smarter about caching last-hit characters. (Annoying; TEdit: TEditMouseImpl).

 Buttons and Menus should only trigger when the mouse is let up in the same item that received the downclick to minimise false triggering (New Feature; Viewers: Menus & Buttons).

 New formatting capabilities for text looks: underlining, better font substitution algorithms, handle characters not in the chosen font, etc. (New Feature; TEdit: TEditFormat).

 ViewerTools should provide an interface that creates a new text viewer iff the named backing file already exists on the disk, otherwise returns NIL. A predicate: DoesFileExist might also be worth making public as well. (New Feature; Viewers or somewhere).
