The user interface needs some fine tuning (white space, font size, colors, layout), history export & history charts, assets list, margin call, explorer ...
It makes more sense to write a list of improvements/tasks and help implementing, than doing parallel a whole new thing.
For you it makes more sense to do the whole thing new.
Implementing some graphic features and fine tuning the interface with new ideas is a good thing, but we should split the UI task in small chunks and consider a regular feedback from the community.
I put some hours of thoughts and feedback, what needs improvement, (list is coming), from people using BTS daily.
The weak spots are on the radar, but we need an extra professional layout/designer/programmer to achieve this, not a whole team. For example the contrast light blue/gray is very bad or there is no more max-width on tables.
What BTS needs is a responsive professional fluid modular styled layout, which works on small, medium and large screen sizes.
In this current form I am against the proposal, but an extra layout/designer/programmer is needed to improve the UI.
