Well, the best solution I found is to use a dropdown terminal (like 
yakuake for example): pressing F12 the terminal appears/disappears. This 
way, I never have to close it and it stays open with a bunch tabs with 
the most common command line applications I use.

Well, I think the .desktop approach is the best one here.
You can also try to use a command launcher: with the Ubuntu I use 
(16.04), I have Alt+F2 that opens a proper command launcher and I can 
run any command line app. Note that it differs from pressing the Windows 
key that will only launch applications that have a corresponding 
*.desktop file.

I don't see your attempt here.
If you installed scilab from the repos, you should have a *.desktop file 
to tinker with in order to call your up-to-date scilab instead of the 
repo one.
On my system the desktop files of the repos applications are here:

     /usr/share/app-install/desktop/scilab:scilab.desktop
     /usr/share/applications/scilab.desktop

while I put the one of the applications I installed by hand  here:

     ~/.local/share/applications/

Hope it helps,

Antoine
