I've now uploaded
Version 4 of the NeoLemmix 12.13 Experimental, which includes a new fall distance ruler for testing purposes.
It now only shows the actual fall distance - no potentially confusing markings or additional measurements. Plus, we'll give the colour cycle a spin and see if we like it (I understand Simon's concerns regarding this, so I'll look at either making the colour cycle optional or only cycling through non-problematic colours).
I'll also be adding the Climber ruler as a separate graphic, callable via its own hotkey and/or by Shift-modding the regular hotkey (currently I), but that's a job for another day.
Please do check it out and offer feedback as the features in this experimental are likely to make it into NeoLemmix, so it would be better if they've been fully tested and discussed prior to final implementation.
