Hi, thanks for your feedback.
Really appreciate you took your time to take a good look at the project
What did you do to get to the blank page? Was this issue on a customised coin/exchange dashboard or on one of the defaults?
The project itself is quite lightweight (runs smoothly locally on old raspberry pi 1's) but due to some bugs that slipped in during transformation of private project (without customisation options) to public it's currently not optimal, currently looking into fixing most of the bugs.
As for not all coin data showing up directly on load (at least for exchangeview) this is caused as the price only updates on active trades, hence not all coins display a value at loading of the page.
I had actually integrated select2 for the coinselection, this should have add a search function to the dropdown menus , however I notice this isn't loading correctly either, will be fixed very soon. (Fixed)
