Dear Fernando,
Thank you for the design proposal, I think your design is very good with a balance of handle positions. We're still missing a couple of options, but it covers the largest use cases nicely.
But I find the interactionvery overloaded of buttons in the video. And I think it becames so complex and not coherent with the old functions.
Your finding isn't unique, it's a known problem which I think you have helped with your proposal :-) thank you. The video is a bit out dated and a similar design to your proposal came afterwards, the debate about multiple clicks to change the mode did point out the break in past function that may cause some concern.
I send you attached an alternative proposal to implement such nice feature in next Inkscape version. Considering the simplest way and more coherent with Inkscape.
Thank you for your help again, hopefully you will continue this design debate with me in the future. :-)
Best Regards, Martin Owens
