• reduce gestures
• smarter editing
• improve presentation of editing and browsing related information
• consolidate preference handling
• consolidate code

Navigation and interaction

Planned items

• folding
  • allow user controlled folding structures
  • vertical ruler column as folding control
• [>3.0] editor view splitting
• regex in Find/Replace dialog (available, needs 1.4. runtime)
• enable reducing the number of gestures required to insert a completion proposal and to continue typing
  • e.g., auto activate content assist if completion trigger is also an auto activation trigger
• interactive status bar
  • change overwrite mode on double click
  • change raw/smart mode on double click (see smart typing section)
  • [>3.0] change read/only flag on double click
• provide actions to show/hide vertical ruler columns, overview ruler, etc. that can be bound to accelerators

Investigation items

• navigation control
  
  • Previous element button, Selector to choose the element type, Next element button
  • navigation hover listing all possible navigation actions as hyper links
  • content assist like lightweight dialog approach listing all possible navigation actions
  • [>3.0] action hovers
• [>3.0] support gestures

Information presentation

• generalize hover concept to show context information of elements and allow for configurable presentation
  • control as hover or view part
  • content as text, list, or tree
• change bar vertical ruler column
  • shows difference to a selected revision/snapshot/saved state
  • ruler hover shows original content
  • context menu offers action to revert the current difference to the original content
    
• background highlighting of text to complement squiggles
• synchronize editor dirty bit and undo manager state

Typing

Planned items

• smart insert new line before/after cursor line
• duplicate selection/line
• [>3.0] transpose lines/words/characters
• move lines
• copy lines
• change selection to upper/lower case
• smart Backspace/Delete/yank line: will remove everything inserted by an auto indent strategy
• [>3.0] delete block of empty lines (keep none or one)
• introduce "raw" mode in which every key stroke is stripped down to its bare meaning
  • mode is shown in the status line
  • action with key binding to toggle mode
  • adapt all actions to consider the mode setting
• template support in Default Text Editor

Investigation items

• [>3.0] investigate macro support (requires command based text infrastructure)

Preference handling

• support default configurations and preference inheritance
• introduce UI for setting the Undo manager stack size

Misc

• [>3.0] allow to specify line terminator for new files
• editors and none resources
  • open editor on a java.io.file rather than IFile
  • [>3.0] support for more abstract editable source than IFile such as IEditableEditorInput

Architectural and implementation issues

• [>3.0] merge interfaces with their extensions including cleanup of replaced concepts
• integrate command based text manipulation with IDocument and related classes
  • unify with the undo manager
  • find policy of partition and position updating that fits compound text manipulation commands
• extend partitioning
  • handle partitions of length zero
  • [>3.0] introduce nested partitions
• move templates to text infrastructure layer
