- Further code optimisations added by dvdvideo1234.
- Tweaked up/down control mixing, should feel more responsive and less likely to get 'stuck' when switching directions now.

Updated steam version to GitHub latest.

"Controls were modified so as to not interfere with other addons. (Smartsnap)
Plus holding shift is easier than left alt."


Changes:
- Unified controls to use SHIFT + LMB/RMB/Reload instead of ALT or E.
- Changed clientside laser rendering to fix offset beams for some models.
- Made the toolmenu look a bit nicer and updated help text.
- Changed the wording of notifications.

Added:
- Tool information HUD now shows more controls when holding SHIFT.

Updated steam version to GitHub latest.

- New stuff:
Attempted a better looking UI for the mouseover popups when looking at a hoverball.
Added option to use parenting instead of welds to attach hoverballs. (Sturdier, but can't be updated by left-clicking)
Added ability to ALT + left click a contraption and update all connected hoverballs at once.
Added experimental "Slippery mode" that makes hoverballs slide down angled surfaces.
Added configuration for Slippery mode under new Experimental heading. (Requires tickbox to enable)
Added ability to visualise the traces with lasers. Can be configured to only show when holding the tool.
Added config option to show the lasers even when not holding the tool, cause I thought they looked cool.

- Changes:
Made a config option for setting hover height with SHIFT + left click. (Off by default)
Moved settings update on left-click code to own function so it can be used for ALT + click as well.
Moved tool settings to their own section. (Tool settings are client-only and not written to the hoverball)
Added small cube (models/hunter/plates/plate.mdl) to available models list.
Changed some menu labels.

- Fixes:
Fixed water detection being broken. (Wrong variable name, my bad.)
Limited hoverball hover height variable from going below 0, as that would be pointless.
Fixed tapping the brake key while HB is disabled clearing the tooltip status display.

Turns out a lot of stuff was broken, but after 16 hours and a lot of coffee I *think* we're good again.
I'm sorry if you were one of the people this has affected.

- FIXED:
- Duplicating seems to work properly now.
- Missing UI labels now show correctly.
- Updating keybinds on existing hoverballs using the tool now works correctly.
- Keybinds now properly save when duplicated.
- One rogue letter causing problems again.

- ADDED:
- Can now copy keybinds from existing hoverballs with right click. (Configurable)
- Can now choose if hoverballs are enabled on spawn or not.

Reverted changes, problems with duplicator breaking stuff.

Merged changes from GitHub version, check out the link in the description for the full list of fixes.

Short version:
- 'Hover over water' tickbox actually works properly now.
- Added sounds for copying/updating hoverball settings with toolgun.
- Can now delete hoverballs with toolgun reload.
- Nicer notifications instead of chat spam.
- Fixed weird issue with hoverballs sometimes needing a little nudge to work.
- Disabled use of brakes when hoverballs are switched off.

Thanks again to dvdvideo1234 on GitHub for their contributions to the code!

Merged dvdvideo1234's changes from the Github version.
Thank you for the help! :)

As requested by a Steam user with a very distressing profile background, hoverballs now change hover height smoothly instead of in steps.
