OCAD Sketch

A crash could occur when opening a project if the position tail is visible, this has been fixed.

New Features: * Sketch colours can now be filtered and sorted - see edit button to right of colours on colours-toolbar at the bottom of the screen. * Zoom buttons can be hidden - see project settings. * The Eraser can be resized - see project settings. * The Sketch layer can be hidden or just dimmed - see layers menu. * All background layers can be shown or hidden all at once - see layers menu. Improvements: * Undo-redo of sketch features now uses a single mouse action as a transaction (previously this was a transaction per feature change). * Sketch features drawing performance has been improved. * Background map sorting now only uses the drag-handle to instigate re-ordering. Bugs fixed: * Position logging on some devices didn't filter on location or time correctly which could potentially lead to inflated logs (a difference of 0.1mm and 1 second is required to log a new position).

Background GPS logging fixed (Note that this may also require allowing "Always" tracking in the Location settings on your device. Note that it may also not work in low-power mode). Distance between north lines can now be a decimal. The erroneous percentage progress indicator shown when downloading a project has been fixed. Minor user interface fixes.

The scale bar calculation for small map scales has been fixed. Use the Settings menu to show or hide the scale bar.
