I use Aegis only as backup because the workflow is cumbersome as you say (the app itself is flawless in my book), my primary TOTP authenticator is KeePass. I use the exact same KeePass setup on Linux, Windows and MacOS and copying a TOTP token is only a hotkey away. My KeePass also acts as SSH agent which also works with Cygwin, MSYS and WSL. On Android I use KeePassDX which also supports TOTP. I almost never ever open Aegis and when I do it's mostly to check that I can remember the password. I sync my KeePass databases across all devices and OSes with Syncthing.
