Long time ago i've faced annoying issue with colors under screen/tmux.
Googling a lot i've found that i'm not alone with this.
In short, colors in apps under screen (im active fan of this app) are significantly broken. I've changed color schemes, terminal settings like

term "screen-256color"
term "xterm-256color"

, hacks of terminal files ..and so on. That issue killed a lot of time and nervous. Solution, as usual, was simple and even "stupid". I'm not sure how that was found, i was thinking about same thing but can't reverse that to understand what was happening.
Finally solution was found here: https://github.com/busyloop/lolcat/issues/117 (thanks a LOT btw)
Fix in my case looks like this:

# vim ~/.bash_aliases OR vim ~/.profile OR ENEN vim ~/.bashrc
# force cleanup of this var
export COLORTERM=

Screenshots with description of issue below

No screen, simple xfce terminal - OK


Broken colors, mc loaded under screen


That painfull pre-set variable


vim ~/.bash_aliases


Saved, restarted terminal, run screen, run mc - colors fixed.

Usually there is a need to save tabs and its folder locations of Terminal to avoid routine everyday actions. There is a different terminals (Windows Terminal is my fav for Win 10), some of them has option to save tabs settings, some of them can't.
In case of Xfce Terminal we have an option to use command line to resolve this issue.
Man is the man, as usual .)

man xfce4-terminal

Tons of interesting things there, but for me this simple line is enough

xfce4-terminal --maximize -T "HOST OS" --working-directory=/home/ijin --tab -T "!! GUEST OS !!" --working-directory=/home/ijin/vagrant-vms/tatuin

Added that to launcher and that is it. Fix paths and tab names for yourself.

In case you have 2 (or more) monitors using for monitoring/stats/youtube/etc it is often case when you need to reduce windows quantity during Alt+Tab (its comfy).
Unfortunateley, there is no such option in Win10/11.
But, thanks God, we're using XFCE. Here you can easily do this with the command

/usr/bin/wmctrl -r :SELECT: -b toggle,skip_pager
# man wmctrl is very interesting too.

As for me, i've made a launcher for this, like this:

One

Two

Calling this command you'll see changed cursor which you have to use for click on the window you want to show/hide from Alt-Tab.
Just like that. No need permanent running external software.

Not so hard, than you can imagine. I've spent some time and prepared working solution right here. Have a nice day!

Easy

sudo netstat -atpn

Or check exact app by name

sudo netstat -atpn | grep -i nginx
