- A homescreen widget that shows your stock portolio in a resizable grid.
- Based off the [ministocks widget](https://github.com/niteshpatel/ministocks) but allowing unlimited tickers in a grid so you don't have to worry about sizing.
- Stocks are sorted by change in percent (descending).
- Stocks can be sorted by dragging and dropping the list.
- Only performs automatic fetching of stocks during trading hours and weekdays.

- Ability to set a custom refresh interval
- Ability to pick indices such as **^DJI**.
- Ability to change the app theme and colors
- Ability to change the way the stocks are sorted or to drag and drop the sort order.
