Making the insert mode indicator more visible and vibrant by default

[txtyash]

I'm aware that one can use css to change the look & feel of vimiumC but having an easily visible indicator would help a lot.
I usually avoid using insert mode for applications like youtube and use the trackpad instead just because the insert mode indicator mostly invisible to me.

Suggestions:

• Place it on top instead of bottom
• Use vibrant colors

You may write CSS rules to adjust the UI, like this:

.HUD { top: 0; font-size: 24px; color: red; line-height: 28px; height: 30px }
.HUD::after{ border-radius: 0 0 8px 8px; }
