Improving the UI of this plugin

[Bharat]

Hello Hidetake Iwata.
I was searching for the bookmarks tab plugin and came across BNTP. It is very useful.
It could have been a lot better if it has good Interface.

Can I contribute my design skills to improve the UI of this plugin? I'm a Product designer with 3+ years of experience in UI, UX and Product Strategy.

Let me know if this can be useful to this project. We can discuss this further.
