files are  displayed as lists in two panels. 
a focused panel (red list header on image) is a ★source★, the other
panel being a ★destination★.
there are rows of buttons beneath the lists to run commands on the files.
★each those buttons can be configured★, and other buttons can be added.

It is costing quite some time to configure a button, ⅈyet it is well
worth itⅈ, since each button made can save ★much★ time.






example
if searching the internet while trying doing something, solutions found
often are some command line.
instead of recording some notes about those command line, they could be
configured as file manager commands.
worker provides some variables to craft commands, named flags. 
they look like letters between braces as 🖬{F}🖬

lets say one occasionally converts picture as lossless .webp

instead of a recorded note being
💻convert   /home/user/pictures/image.gif -define webp:lossless=true
/home/user/pictures/image.webp💻
and having to adapt it each time it would be useful,

a worker command looks like:
💻convert {uf} -define webp:lossless=true {op}/{fE}.webp💻

a button can be configured with such a command, see below [#0]:

then later on, converting the picture only goes with a few click:
some to select source, some to select destination, one to convert.

in the example command, flags mean:
🖬{uf}🖬 filename without path, keeping it selected
🖬{op}🖬 other path (destination path)
🖬{fE}🖬 filename without path, without extension, deselecting it.

configuration
a button can be configured:
🖬Worker Configuration🖬 > 🖬Button settings🖬 > 🖬Button
Configuration🖬
choose an empty button with a click

an 🖬Edit button🖬 window pops up -see images-
enter as 🖬Button title🖬 it could be named 'ⅈconvert as webpⅈ'
then click 🖬Add command🖬 > 🖬own command🖬

an 🖬Configure own command🖬 window pops up -see images-
enter as 🖬Program🖬 💻convert {uf} -define webp:lossless=true
{op}/{fE}.webp💻

with such a command, "ⅈconvertⅈ" handle a file at a time.
If wanting it operating on multiple selected file with worker, tick
🖬Separate each entry🖬: while used the program command will be re-run
once with each selected files, deselecting each line next doing.
the gadget with 🖬{}🖬 lists usable flags .
