- in CNCJob UI Autolevelling - added a mini gcode sender for the GRBL to be able to send the probing GCode and get the height map (I may make a small and light app for that so it does not need to have FlatCAM on the GCode sender PC)
- in CNCJob UI Autolevelling finished the probing GCode generation for MACH/LinuxCNC controllers; this GCode can also be viewed
- cleanup of the CNCJob UI; added a checkbox to signal if any append/prepend gcode was set in Preferences (unchecking it will override and disable the usage of the append/prepend GCode)
- the start Gcode is now stored in the CNCJob object attribute gc_start
- GCode Editor - finished adding the ability to select a row in the Tools table and select the related GCode
- modified the visibility change in Excellon UI to no longer do plot() when doing visibility toggle for one of the tools but only a visibility change in the shapes properties
- replaced some icons in the app
- in Code Editor, when changing text, the Save Code button will change color (text and icon) to red and after save it will revert the color to the default one
- in Code Editor some methods rework
- added multiple algorithms for path optimization when generating GCode from an Geometry object beside the original Rtree algorithm: TSA, OR-Tools Basic, OR-Tools metaheuristics
- added controls for Geometry object path optimization in Preferences
- Drilling Tool - working in adding tools auto-load from Tools DB
- some updates to the Excellon Object options
- Drilling Tool - manual add from Tools DB is working
- updated Drilling Tool to use the new settings
- updated the Excellon Editor: the default_data dict is populated now on Editor entry
- Excellon Editor: added a new functionality: conversion of slots to drills
- Excellon UI: added a new feature that is grouped in Advanced Settings: a toggle tools table visibility checkbox
- fixed bug that made the selection box show in the stage of adding manual gaps
- updated Cutout Tool UI
- Cutout Tool - in manual gap adding there is now an option to automatically turn on the big cursor which could help
- Cutout Tool - fixed errors when trying to add a manual gap without having a geometry object selected in the combobox
- fixed partially the Excellon Editor to work with the new data structure
- fixed Excellon export to work with the new data structure
- fixed all transformations in the Excellon object attributes; still need to fix the App Tools that creates or use Exellon objects
- if clicking the activity icon in the status bar and there is no object selected then the effect will be a plot_all with fit_view
- modified the FCLabel GUI element
- Geometry UI - minor updates in the layout; moved the warning text to the tooltip of the generate_cncjob button
- Geometry UI - working in making the modification of tool parameters such that if there is a selection of tools the modification in the Tool parameters will be applied to all selected
