guake-terminal for a full-screen overlay terminal, I have a keybinding for transparency toggle so I can read guides through the overlay. I used to use tilda, but I switched because they weren’t supporting wayland.
For random/ad-hoc terminals I’ve historically used gnome-terminal and console, but recently I’ve been trying to eliminate window decoration entirely, and for that I’ve been liking black box (flatpak) for the floating decoration and other configuration bits.
They both support theming, and have dracula included by default, so it was easy enough to get a consistent look and feel.
I have tabs switched off for all of them. That’s what tmux is for.
Not sure if you knew, but Yakuake is very similar to tilde from what I've heard and has worked flawlessly for me on Wayland. https://apps.kde.org/yakuake/
I have, I think the one time I tried it (5 years ago, on a different machine, os and X11), it wasn’t snappy enough. Probably time to go back and check it out!
Guake has this annoying bug on wayland gnome where the interface complains that ‘keybindings can’t be set’, so you control it through custom keybindings that run terminal commands to show and hide the terminal.
There is a gnome extension ddterm which works under Wayland and works like guake. But unfortunately it currently does not support the latest version of gnome yet.
