Uso anche una combinazione di riga didascalia / hardstatus abbastanza coinvolta, per simulare l'effetto delle schede a discesa (la riga della didascalia è grigia e la scheda corrente nell'hardstatus è dello stesso colore).
Ho anche la mia shell dire allo schermo qual è il nome del processo corrente e in quale directory mi trovo, quindi i miei nomi delle schede rimangono aggiornati con quello che sto facendo in ogni scheda. Questo è fondamentale per ricordare cosa sto facendo dove senza dover sfogliare tutte le mie schede aperte.
# don't use the hardstatus line for system messages, use reverse video instead
# (we'll be using it for the list of tab windows - see hardstatus alwayslastline
# below)
hardstatus off
# use the caption line for the computer name, load, hstatus (as set by zsh), & time
# the caption line gets repeated for each window being displayed (using :split),
# so we'll use color cues to differentiate the caption of the current, active
# window, and the others.
# always - display the caption continuously. Since
# hardstatus is 'alwayslastline', it will be on the
# next to last line.
# "%?%F" - if (leading '%?') this region has focus ('%F')
# (e.g. it's the only region being displayed, or,
# if in split-screen mode, it's the currently active
# region)
# "%{= Kk}" - set the colorscheme to blac[k] on grey (bright blac[K]),
# with no other effects (standout, underline, etc.)
# "%:" - otherwise ('%:' between a pair of '%?'s)
# "%{=u kR}" - set the colorscheme to [R]ed on blac[k], and
# underline it, but no other effects (bold, standout, etc.)
# "%?" - end if (trailing '%?')
# " %h " - print two spaces, tthne the [h]ardstatus of the
# current tab window (as set by zsh - see zshrc) and
# then another space.
# "%-024=" - either pad (with spaces) or truncate the previous
# text so that the rest of the caption string starts
# 24 characters ('024') from the right ('-') edge of
# the caption line.
# NOTE: omitting the '0' before the '24' would pad
# or truncate the text so it would be 24% from the
# right.
# "%{+b} - add ('+') [b]old to the current text effects, but
# don't change the current colors.
# " %C:%s%a %D %d %M %Y" - print the [C]urrent time, a colon, the [s]econds,
# whether it's [a]m or pm, the [D]ay name, the [d]ay
# of the month, the [M]onth, and the [Y]ear.
# (this takes up 24 characters, so the previous
# pad/truncate command makes sure the clock doesn't
# get pushed off of the caption line)
# "%{= dd}" - revert to the [d]efault background and [d]efault
# foreground colors, respectively, with no ('= ')
# other effects.
# other things that might be useful later are
# " %H" - print a space, then the [H]ostname.
# "(%{.K}%l%{-}):" - print a '(', then change the text color to grey
# (aka bright blac[K]), and print the current system
# [l]oad. Then revert to the previous colorscheme
# ('%{-}') and print a close ')' and a colon.
# NOTE: the load is only updated when some other
# portion of the caption string needs to be changed
# (like the seconds in the clock, or if there were a
# backtick command)
# "%0`" - put the output of a backtick command in the line
# "%-024<" - don't pad, just truncate if the string is past 24
# characters from the right edge
# "%-=" - pad (with spaces) the previous text text so that
# the rest of the caption string is justified
# against the right edge of the screen.
# NOTE: doesn't appear to truncate previous text.
caption always "%?%F%{= Kk}%:%{=u kR}%? %h %-024=%{+b} %C%a %D %d %M %Y%{= db}"
# use the hardstatus line for the window list
# alwayslastline - always display the hardstatus as the last line of the
# terminal
# "%{= kR} %-Lw" - change to a blac[k] background with bright [R]ed text,
# and print all the tab [w]indow numbers and titles in
# the [L]ong format (ie with flags) upto ('-') the
# current tab window
# "%{=b Kk} %n%f %t " - change to grey (bright blac[K]) background with
# [b]old blac[k] text, with no other effects, and print
# the [n]umber of the current tab window, any [f]lags it
# might have, and the [t]itle of the current tab window
# (as set by zsh - see zshrc).
# NOTE: the color match with the caption line makes it
# appear as if a 'tab' is dropping down from the caption
# line, highlighting the number & title of the current
# tab window. Nifty, ain't it)
# "%{-}%+Lw " - revert to the previous color scheme (red on black)
# and print all the tab [w]indow numbers and titles in
# the [L]ong format (ie with flags) after ('+') the
# current tab window.
# "%=%{= dd}" - pad all the way to the right (since there is no text
# that follows this) and revert to the [d]efault
# background and [d]efault foreground colors, with no
# ('= ') other effects.

Quindi ecco le mie impostazioni di zshrc per dire allo schermo cosa sto facendo in ogni scheda.
