Add tooltips that explain how everything works
Let a user filter to markets in which they have positions
If the user enters a date, it should be treated as a range from the beginning of that day to the end, not just the single millisecond at which that day begins.
Make the choice of which markets to store locally smarter, so it won't accidentally cross the 5MB localStorage limit.
Add proper inputs for dates and drop downs for categories
Multi-buy in multiple-choice markets
Add a quickbet button where the user inputs their expected probability, and it calculates and places the appropriate Kelly bet size based on their portfolio.
Add a tiny graph/sparkline on each row to show how the market has changed recently
Generate RSS feeds for user-specified queries (like https://hnrss.org/newest?points=100)
Add support for arbitraging similar markets/answers, either treating them as summing to 1 or specifying a target relative change percentage.
Make a userscript that overrides Manifold's default search with Isaac's search
Add an option to display each answer on a multiple-choice market as its own row in the search results.
A column to display the market price X amount of time ago, input by the user
Allow users to define more than one dashboard, and share them via URL with other people
Option to show dates in a standardized day/hour/minute format that all lines up
Add a filter to only show markets the user hasn't seen before.
Make the search boxes look nicer so they're not just a giant pile of input boxes. Lay them out in columns or hide ones the user isn't using or something.
Add an OR conjunction for search terms, so people can search for something like "question includes 'altman' OR 'OpenAI'"
Open markets in new tab by default
Add a "concise mode", which removes all extraneous text from the table, like the percent sign, M$ sign, etc. and aligns them all nicely
Add fuzzy searching that can catch typos and synonyms
Let people resize columns, or add intelligent column resizing
Let people see the limit orders of a selected user in each market
Dark Mode
Add support for other platforms. Polymarket, Kalshi, etc.
Add tiny arrows in each column header as a visual indicator that they can click there to sort the column
Let people see the position of a selected user in each market
Add reminders to check back on a market after some time
Add direct links to user profile and/or group pages, maybe accessible by shift-clicking on them.
Check to see if any of the code has changed upon page load, and if so wipe the cached market data and reload it.
Let people see the profit of a selected user in each market
Fix the graphical issues that cause fields to unfocus and dropdown menus to disappear each time new data is loaded
Add some way for clicking on a group or creator to wipe the rest of the search. Maybe shift-click? Or maybe it should be the default?
Add more complex diff detection so that the client can catch up on what it missed if it loses internet for a few minutes, or at least tell the user it's out of date
Add hotkeys to make trading and searching even faster
Add more sensible step values to the numeric input fields
Allow people to place long-term limit orders
Make the "last updated time" field include edits to the market description
Somehow convince Manifold to waive the API fee if bets are placed via Predictionary
Make it look not-terrible (this suggestion is for aesthetics only, not functionally-useful layout/display features)
Allow users to see whether a multiple-choice market is select-one or select-multiple
Display who can add answers on a multiple-choice market
Give it a better name than Predictionary. (Suggestions welcome.)
Add support for Polymarket front-running. (https://medium.com/@eightyhi/blockchain-based-amms-arent-fit-for-prediction-markets-bbe6ad7a33ca)
Make a row flash when its probability changes
Add a bulk bet button that can bet on all markets in the dashboard
Fix the bug that causes some resolved markets to not be marked as closed
Add a way to view/query detailed historical market data
Add a one-click feedback form on the page itself
Fix links to Manifold markets (currently all links go to "/{username}/undefined")
Add a filter/sort by recently subsidized
Add an option to change the height of each row such that it's proportional to the width of the interval between the previous market's close time and the next market's close time, so distance down the page represents time in the future.
Fix the bug that causes numeric markets to be displayed as though they were regular percentage markets.
Include all unlisted markets
