ANTE: Stake on this to subsidize the market.
The ability to look for related markets in the API.
Linkable Comments
Ability to optionally privately enter your expectation of outcome when making a purchase, for the purpose of having a personal calibration curve. Justification: I find that making calibration curves for myself is fun and helps improve my forecasting, and that my calibration curve gets less accurate after a few months if I stop practicing. But the practice takes effort, which could be piggy-backed on the forecasting activity of participating in prediction markets for less effort than doing it seperately.
Reminders. Allow users to set a custom reminder to return to a market.
Spoiler tags to hide markets about in progress fiction
Merge duplicate Answers for multiple Answer Questions https://manifold.markets/Honourary/will-manifold-markets-add-a-merge-f
Ability to short multiple choice answers
Retroactively close a market, undoing bets after the new close time. (Reward predictions before the events happened, not betting really quickly after hearing the news.)
Resolve market to probabilities other than market probabilities. Useful for betting on outcomes of other markets.
Short answers on free response questions
Graph showing the pool size of a market over time
A meta-market. Simple exchange that lets you place a bid/sell order for shares of whatever market.
Set a time to stop allowing creation of new free response answers separately from the market close time
We need numerical range questions. Many topics are way more informative when expressed that way, over a Yes No.
Ability to tip users M$ for helpful comments.
Ability to attach (private) personal notes to other users (e.g. to keep track of who you've observed be a good market resolver)
Ability to include a short message when resolving a market
A "poll" category of market. You can buy as many votes as you want but the payout is unrelated to which answer wins. (Could be zero, could reverse the system so bettors get 4% and the creator gets the balance, or something else.)
Reducing the number of personal questions (eg. "Will I do ...")
Market Indicies, Allowing Multiple Markets to Be Combined Into One and Automatically Weighted with Drag and Drop Type Feature
Show currently placed on market overviews, like https://manifold.markets/markets (it is easy to forget where loans were used)
Allow to exclude communities/tags on feed/market overview. It would be nice to not have ability to skip all this gambling ("yes iff pool divisible by 2" etc)

Reduced fees for long horizon markets to increase trading volume.
Upload photos with comments. Useful for proof of results and other fun things.
I would like there to be a feature that integrates something like an RSS feed. If key words or phrases about specific event occurs, trading is suspended until the market is either resolved or the RSS notification is tagged as a false positive. As what often happens, the gains of many bettors are wiped out by slow resolutions of markets.

The ability to subsidize markets, putting up money to enhance liquidity and encourage participation, without taking a particular side of the bet. (The thing that the ANTE option on this market is trying to do, just in a more formal and less ad-hoc way, which would also work for YES/NO markets.)

Earn interest on M$ tied up in long time horizon bets.
