The form to add new environment variable in the environment variable page of any project is completely unusable.

When i want to set a variable specific to a preview branch:

1. It's extremely confusing that now environment and git branches are shown as under same dropdown with braches. screnshot-1
2. The search filter in the branch selector of preview branches DO NOT WORK at all. One needs to manually scan the list and hope they find the branch or type the full branch name. screenshot-2 (and observe the text overflow)
3. One needs to go back after selection of preview branch and toggle off environments that do not apply. It's such a waste of effort.
4. The dropdown design is atrocious and confusing.

TLDR; Fix your new environment variable form. It's very annoying to deal with.
