The same part of me that is shy to install Chrome extensions is shy to try non-standard terminals. I'd like the thing I type my passwords into to be as trusted as possible.
SteamOS comes with Konsole, so that's what I've got installed in Linux. What am I missing out on by not using e.g. Ghostty?
(I know this article is about Unicode support, but I don't think I've ever had a hard time using a terminal because of its level of Unicode support.)
So, don't type your password into your terminal emulator? In many situations (ssh and suchlike) you can use another means of unlocking your credentials.
If Konsole suits your needs, there is no reason to move to Ghostty. You may find better performance or access to more terminal features, but if those don't move the needle for you, then it doesn't matter. Konsole is well integrated in to KDE.
