TODO

This file contains enhancements the developer and user community would like to see:


Planned for 3.4.x
- Bug fixes
Planned for 3.5:
- (What is the problem here? Run is shown, then Idle when stopped) Detect machine state at end of run and display it properly (i.e. "transitioning" when it is still moving)
- Every second or so, if not scrolled to bottom, scroll to bottom of status
- Allow reload of same file from same location
- After a run, suppress $$ output with a single line
- Report system settings at beginning of log file. Include OS.
- Can't see drill holes under axis, move axes under toolpaths?
- Create test plan (i.e. verify all text appears correctly on all platforms)
- Display detected version of Grbl
- Speed limit for X and Y like the Z speed limit

Planned for 3.6:
- Implement support for Grbl 0.8c "homing" feature (using limit switches)
- UI support for homing limit switches
- Restore "Tool change" feature, including popup dialog
- Option to engage stepper lock (include fade out rate setting - start time of fade, end time of fade, requires hw mod)
- Display current feedrate in mm/sec or in/sec
- Add additional rs232 error logging value (-1 is not very useful)
- Analyze file ahead of time and determine if it will go beyond extents
- Update manual since 3.3

Planned for 3.7
- Switch to compiling using Qt 5
- Auto-scale widgets to full screen size
- Localization ready code
- Don't fail on timeout waiting for command - let user continue if they want
- Pick up from where left off (if GC dies due to PC falling asleep, etc.)
- Look at all hardware connection options of Grbl on the shield and make
  sure that we have some way to control those, i.e. spindle control.
- Clear log button
- Print current GRBL settings
- Add option to always use last working port, even if it isn't currently connected

Primary:
- Save/Load current GRBL settings from disk
- Suppress some bookkeeping output from the status window
- Add local Help linked from main screen and options dialog
- When parsing for visualizer, if bad value arg, warn user
- If nothing appears in visualizer, attempt to diagnose and explain to user
- If get error from grbl, provide command that generated error on same line
- Allow user to choose how to handle unspecified units in file for visualizer
- Fix Zero position next to begin?
- Show drill holes as larger dots?
- Build in calibration pattern
- Build in "flatten table feature"
- File viewer
- Estimate bounds based on both toolpaths and tool diameter, not just toolpaths

Secondary:
- Make GC generic to support controllers other than Grbl
- Recent files list under 'Files'
- Restore "Favorites" feature
- Provide diagnostic response view
- Provide counter showing time waiting for a response if time > 5s
- Estimated time to completion (this can acutally be computed from feedrates)

Notes pulled from https://github.com/grbl/grbl/issues/202

Move Z to upper clear position. (<- another parameter?)
Stop the spindle.
X and Y to the change tool coordinates.
A way to adjust new Z (manual for me) and perhaps new speed for the spindle (manual for me).
When ready (~) start cycle? to continue with the new tool with the same X and Y initial coordinates than the last tool.
