Kitty has a very nice way to search and insert unicode characters (shift+control+u).

I tend to use the CTRL+Shift+U shortcut with the codes memorized or looked up from https://unicode.org/charts/ (https://odoepner.wordpress.com/2018/01/04/enter-unicode-char... goes through how to use it) instead, so I can use them all over (IRC + Slack + Browser + Terminal).

Good to know though, so thanks for the reply.

Tabs are probably the biggest thing.

One thing about tabs, which ironically has come up now for Microsoft Windows Terminal, is that they do not fit at all well with the idea of application-resizable terminals, which has been the widely case for terminal I/O since the days of 80/132 column application-switchable terminals back in the 1970s. If (just to pick a mild example) one tab is a 24-line terminal and another is a 25-line terminal, they aren't the same size in the GUI.

Line up a row of real terminals, and of course they do not constrain one another, size-wise. Indeed, back in the 1990s the DTTerm terminal emulator pioneered the terminal emulators' abilities for applications to set any arbitrary size (within reason) for a terminal emulator.

I did a quick review of terminal emulators in light of this, and varyingly tabbed terminal emulators do not support application resizing (DECSLPP/DECSNLS/DECSCPP) at all or support it in limited, or at least odd (compared to real terminals), ways. Konsole, possibly the best of the bunch, implements resizing properly, leaving large margins when the requested terminal screen size does not match the GUI window size, but triggers a GUI resize whenever a tab receives the input focus back, so application-requested size changes do not last if one switches amongst tabs. One tabbed terminal emulator author is actively opposing the idea that terminals should be resizable by applications emitting these control sequences, completely reversing course from DTTerm's innovation.

The problem for Windows Terminal is compounded by the fact that it isn't just supporting terminal I/O applications, it is supporting console I/O applications. In console I/O not only can applications set the screen buffer size at whim, they can also set the window rectangle. Not supporting either is a huge and very noticable step backwards, by over three decades, for Windows TUI applications that Windows Terminal is aimed to be compatible with.

A tabbed UI is not a universally unproblematic thing when it comes to terminal emulators. (-:

I see. For someone using tmux, seems that would be a non-feature. Thanks for the reply!
