Hey T212-mates,
I am Saud from Kingdom of Saudi Arabia. I love Trading 212 platform It opened whole a lot of markets and stocks. So I would like to type my thoughts on features to improve the platform.
Here they are:
1- Resolve returns on all portfolio or pies’ to be accurate instead of being calculate once again when an investments made.
2- Revamped Auto self-balanced for pies with original contribution capital not with total value include profits and dividends.
3- Show Stocks initial purchase prices beside total value and returned inside pies. because each pie has different price point and the investments tab shows the average price for all.
4- Create pies inside a pie and moves current pies inside current pies 
.
5- True Dark theme to take advantage of OLED display in iPhone beside the current ones.
6- show ETF’s expense ratios.
7- Auto Invest inside a pie for small dividends as low as $0.01. not everyone is packed with much stocks hahah.
8- Split Pie’s stocks from the Investments tab with non-pie’s.
9- Create Savings account with Interest feature in free fund amount for encourage investors so save their money inside the platform instead of banks and ready to take any opportunity.
10- Specify dividends for each pie in dividends tab (history page). Know each pies how much bring each month.
11- Enable limit sell for fractional shares (now only support full share)
12- Update T212 iPad app for iPadOS its so important to use an iPad than an iPhone. Beside you are going to kill two birds with one stone now, iPhone and iPad apps supported in Macs and macOS.
13- Split CFD - Invest - ISA into three differents apps each app has its own stocks and requirement features available for it.
well, that’s all what I can think of
Cheers,…
