I am using Android Studio which is basically InteliJ Idea with Android SDK. Since I cannot find a site to submit suggestions for Android Studio, I think I could use this site.
Default scheme is too bright in a dark room at night, so I use Dracula at night. But Dracula is too dark at daytime, so I manually change the scheme to the Default scheme at daytime. And I repeat switching the scheme day and night... I wish there was a feature to do that automatically. It is sort of the night mode, which recent mobile OSs are beginning to adopt (iOS has Night Shift and CyanogenMod has Night Mode).
