Weight Painting Workflow imporvement ?

These are some nice suggestions. I think you should add them as bullet points in your post.

I will bullet point these for easy reading

Improving weight painting for 2.8 suggestions by panicq06

• When in solid mode using studio lightning for example, it's harder to see the mesh wireframe in 2.8 as opposed to 2.7
• No add/subtract tool in the default weight-painting toolbar, it instead hides in the toolbar making it 2 clicks if you're using the draw tool or 3 if using another tool - this is a problem because those tools are used the most. You also can't add a shortcut to them.
• Weightpainting undo is slow (possible bug)
• White and dashed wireframe was easier to see than the one we have now (orange solid)
• No easy way to enter a "weight painting mode" where the visuals are optimized for weight painting (he created an addon for this to show how it would work: Before hitting "Enter WP" it looks like the first picture below and while in weight painting mode the second picture)
• Exiting WP mode would also remember the selections that were active when entering - this allows for fast adjustments when going between weight painting and posing
