Instead of returning two differents objects "data" and "includes" when calling endpoints like search tweets, it would be much simplier to have all the data inside one object.
Currently we have :

  {

  data:[

        {

           // tweet 1

        },

        {

           // tweet 2

        }

     ],

  includes:{

        users:[

           {

              // user 1

           },

           {

              // user 2

           }

        ]

  }

better solution would be :

  {

  data:[

        {

           // tweet 1

                 // user 1

        },

        {

           // tweet 2

                 // user 2

        }

  }

Academic researchers often have multiple projects in development at one time, often surrounding the same topic and/or use case. Allowing researchers to have multiple research projects at once or to close out their single project and apply for a new one would help researchers to harness Twitter's data and derive insights more efficiently.

Twitter’s terms of service requires us to delete tweets we have collected when they are removed from Twitter. This makes academic research on certain topics practically impossible, as continually monitoring whether a tweet is still present is unfeasible, and much time could be spent on research that would to be have to have to be abandoned because using the data would violate Twitter’s terms of service. Could an exception requiring the deletion of tweets to the terms of service be made for academic research?

The sample operator that exists for Enterprise would be very useful for v2 Academic Access too: https://developer.twitter.com/en/docs/twitter-api/premium/rules-and-filtering/operators-by-product

I would like to study who networks of bots tend to follow, but since they are quickly suspended this data doesn't seem to be available anywhere.

Current tweet volume for academic research is high. But sometime a need may arise to access larger volume of data. This may not happen throughout the year, but at some point in the research cycle. To support this need:
1) Cumulative volume cap can be kept for four months or six months instead of per month.
2) Certain research projects where the objectives are well defined and transparently reported through means like pre-registration of studies, higher volume access may be granted, through certain means.

I would love to have an endpoint which will allow me to search for accounts based on criteria like keywords in bio, location, min follower count, etc.

Measuring change over time is a fundamental research design. Having timestamped data on follows (A follows B at t) and likes (A likes X at t) would be immensely valuable alongside existing timestamped data on tweets and retweets.

Privacy features for example on a public account being able to hide my followers or vice versa. Privacy screens like they have on Reddit for porn. It would be nice to tweet from my account stream with Porn being blurred when it needs to be blurred.

I request the Twitter to allow access to all the replies of a tweet (all the conversations of a thread). It would be very useful for academics working in user behavior analysis, argumentation mining, hate speech detection because comment or reply reflects the actual thought process of a replying user.

Twitter has launched some labels for Tweets that contain misleading information. For example, under those suspicious tweets, a label named as "Get the facts about.." will show up. However, these labels are not visible in the current json file. These labels are actually pretty interesting and valuable features because we can study the impact of it on the cascade of the misleading information, which will contribute to the current information cascading literature.

Academic researchers should have to submit a statement of ethics declaring their work with Twitter data will not be harmful to oppressed and marginalized people, who are disproportionately harmed by unethical data research practices. Twitter should also make the statements available to the wider community so other folks can learn from them or get ideas for modeling their own statements.

At the moment there appear to be two archive downloads. One from the Account page and another from the Your Twitter Data page. The first comes as a zip file with a nice index.html viewer. The second includes a lot more data but lacks a viewer. It would be useful if these options were combined into a single archive download that contains a usable viewer for the complete data.

This is important for archives that would like to accept snapshots of user's social media content for preservation and research.
