I am curious, are those icons rasterized on the fly or only once and then cached? I mean, rasterizing every icon as 3D object in real time would consume a lot of resources, wouldn't it?

@konstantin (miller) The devs are trying to create more screen space by removing the current toolshelf and replacing it with a toolbar. I'm sure though they will appreciate your thorough feedback.

Please do not add those BIG buttons to the new ui, we need more screen space. Also transform icons don't looks great, move icon looks like a d!ck

@William Reynish (billreynish) thx for letting me know! so that means all those worried pros can tweak them however they want, if they want to, right? Are the icons itself generated while building or loaded dynamically at startup?

Yes, the icons are actual 3D geometry. That's why you can zoom in and they still look sharp. Here's a view at an angle :)

@Pablo Vazquez (venomgfx) I know it's wip, just wanted to document some of the feedback users gave.. I didn't even expect that my tweet would gain that much attention, othervise I would have added more informations about is being wip ;D I personally like the icons soooo much, because they really improove blender's ui and give it a super modern look. Thank you and the team for the great work. Means a lot to me and many other users!

Yes, we probably should fix this issue regardless, yes.. The little ring it also very hard to select. You have to hit the ring exactly, it doesn't register if you drag from anywhere inside it.

Color change on mouse hover (From desaturate to color) is bad practice. instead of changing icon color on mouse hover or pressed, just change background color.

• Icons being too large(Most frequently pointed out by the users)

To avoid unnecessary gap between icon and text, especially in this case that have similarity with the appearance of a list (icon = bullets), the text should be aligned to the left

@Jim Morren (JimMorren) thx for summing up a bit of the discussion that happened on twitter at: https://twitter.com/_3Descape/status/989234428315623424.
A lot of users like the new icons, while many complain about one of the following points:

I took a few minutes during my break time to really analyze the icons. This will be directed and to the point feedback, do not assume I'm under-appreciating the efforts by the devs.
