I found myself struggling quite a bit trying to see the lines and handles of the assistant tool ending many times adding other line instead of grabbing/editing the previous one, on single color there is no problem, but when I have some painting done is really difficult to see, I wonder if there is a way to change the thickness of the lines or to make them brighter a least on hover, I tend to use the spline often and put together a few lines to make some paths, I don't know how many (or if any at all) users are in the same boat, therefore my questions are: A) if this is possible as for now (some hidden setting) if not, B) is there any plans on enhancing (visually) this feature? also C) is there a way to cancel a spline once one click is done? I would think that "Esc" would do it but it doesn't, a least not on my machine. and finally D) is there any plan on making it possible to keep adding splines (like a path tool in other programs) with out the need of putting them together manually?

I would appreciate any comment on this, if there is no possible changes for this now or anytime soon then I can focus on workarounds on my workflow. Thanks!

A). No, the the handles are supossed to light up though.
B). The problem you describe is more likely part of your screen resolution being very high. Once we can get Krita to adapt itself to high resolution screens, I'll personally look into scaling the lines so they'll become visible on higher resolutions.
C). No there isn't, when it comes to hotkeys, assistants are in a lonely spot.
D). Not currently, I can add it to the list of assistants things I'd want to do, but that list is pretty long already, and I won't be working on them coming half year(too many other things on the scedule).

Quiralta: that is an interesting point. We did style one of the assistants in Krita 2.9 after some feedback. Try to turn on the horizontal and vertical mirror tools in the toolbar. Is that closer to what you are thinking? The one issue with those tools is if you paint a lot of grey, the dotted lines styles will get lost. The larger the guides get, the more they will get in the way of your artwork too. Maybe the handles can be filled in with white so they are easier to spot.

TheraHedwig: Thank you for the input, I have two systems that I use, one with kde4 and the other with the kf5 plasma, both running krita 2.9, both show the handles the same, they became opaque once I grab one but there is no light up. As for the rest I was mostly curious, I mean if I can see the handles the rest would not be an issue i think, may be in the future I can also upgrade my hardware, my little penpad push me for the use of this tool quite often for better lines strokes while keeping with the brush dynamics and pressure (which I like a lot from this tool).

scottpetrovic: That handle is way easier to see , wouldn't be bad to have something similar (color wise), but a bit transparent I guess.

As for the lines, I was thinking something more like the "marching ants" in the selection tools, even just static, the white and black dots makes it easy to spot on any background. Again, just some ideas and questions that poped up out my mind while drawing, you guys been doing an awesome job with this software, shouldn't ask for anything else, but just in case there is my feedback.

Hello,

I love your software, I praised its merits as possible, reminding people that while free, you can donate.

But using assistant tool is very difficult because the lines and control points are too subtle. Vanishing points should be colorful and always visible when drawing the lines, even when they are in the canvas. The lines, when we positions them should be filled and wider lines, otherwise a larger dashed. I do not want to advertise an application for which I have no connection, but look how "lazy Nezumi" colored lines for the axes.

Thank you for all the work, I very much regret not being able to write code and help you.

Win 10, Krita 3.0, and a lot of ram
