git-annex is in a mode of continual user-driven improvement, involving numerous small issues and often easily implemented ideas.

Here are some larger/ongoing plans for git-annex, in no particular order.

Speed improvements, including:

Improvements to tree export support, including supporting export to more external special remotes, exporting only preferred content, more efficient renames, and improving support for exporting non-annexed files. https://git-annex.branchable.com/todo/export_preferred_content/ https://git-annex.branchable.com/todo/export_paired_rename_innefficenctcy/ https://git-annex.branchable.com/todo/Exporting_with_exporttree_should_sync_files_deleted_from_the_remote/

Complimenting tree export, support importing trees from special remotes so eg a S3 bucket of data can be pulled into a git-annex repository easily, and the repository updated when the bucket is changed. https://git-annex.branchable.com/todo/import_tree/

Improve support for branches where annexed files without content locally present are hidden (adjust --hide-missing). Including interface for operating on hidden files to get them, speeding up generation of the branch, and updating it more frequently. https://git-annex.branchable.com/todo/better_way_to_get_missing_files/ Also unify adjusted branches and view branches. https://git-annex.branchable.com/todo/unify_adjust_with_view/

Improve Windows support. Long filenames may be possible on Windows now thanks to fixes in recent versions of ghc. Further improve using git-annex in Windows Subsystem for Linux (WSL). Get Windows fully supported with no caveats. Possibly even supporting indirect mode with symlinks. https://git-annex.branchable.com/todo/windows_support/ https://git-annex.branchable.com/todo/utilising_the_mklink_command_on_windows_to_utilise_symlinks_and_therefore_indirect_mode_on_windows/

Add more special remotes, and/or ship a collection of existing external special remotes as part of git-annex. Improve existing special remotes, eg adding support for Glacier lifecycles to S3. https://git-annex.branchable.com/todo/wishlist__58___Restore_s3_files_moved_to_Glacier/

Deltas to improve transfer of modified versions of files. https://git-annex.branchable.com/design/assistant/deltas/
