Preinstall Fastlane on Android Docker images
Is it possible to preinstall Fastlane on Circleci Android Docker Images on your side? I am sure there are some small percentage of people who are not going to use Fastlane on Android Docker, but most people coming to Circiel CI are trying to do CI/CD. Having Fastlane preinstalled make it easy for everyone. Bitrise (your hosted mobile ci platform competitor ) has already been doing this. https://github.com/bitrise-docker/android/blob/master/Dockerfile CCI-I-521
Support Major Version Tags
For Docker Convenience Images, support major version tags, such as cimg/node:15 for the Node.js image.
Cache Brew Install (MacOS)
It would be amazing to be able to cash the expensive 'brew install' operations. These actions eat a large amount of the "credits", which is exacerbated by the fact that MacOS consumes them at a rate of 5x.

Add official support for R
The R programming language is a rapidly developing language which gained lots of new users in the last years. Coming from the statistical field, its scope has expanded nowadays. Especially the usage in an academic context increased in the last years. R is also used for writing books, creating professional reports, developing UI applications or performing machine learning tasks. Organizations like ropensci or r-lib are great examples of immense open-source effort to advance the R community. Besides these, many developers started developing packages (> 10k open-source packages exist) in the last years and see the need for a CI testing suite. Until now, there is only support for R on Travis CI. I see a lot of advantages in how Circle CI runs builds compared to Travis CI. Hence I would love to see official R support for Circle CI. Among others, this additions would result in reduced build times due to the existence of a cached docker image. Furthermore, having a second CI provider for the R community would give the R community more flexibility regarding their CI provider choice and also put some load off from Travis CI. There have been recent efforts to optimize the support for Circle CI within the R community. Examples are packages like tic or the API-client package circle. CCI-I-1221
