Hello @Mohammad,
the Commander Plugin is a very good an powerful tool 
- it makes life easier 
Using it, all affected tiddlers will be tagged with $:/tags/Commander/Working
Is it possible to remove the tag automatic again, when finished?
Thanks
Stefan
Absolutely! When you do selective operation, the working tag is added, with no selective operation, working tag is not added at all!
To remove the working tag, just open the $:/Commander, then check Selective operation? under select tiddlers, and then click unselect button! No matter your filter input is empty, no matter the tiddler is existed or not! Just click on unselect button!
Hello @Mohammad,
you are right - good hint, good to know
Each time by clicking “Select all” / “Deselect all” of tiddlers the field modified will be updated.
Export tiddlers will also update modified - which isn’t correct. 
Tried to switch it off with $timestamp=no in
$:/plugins/kookma/commander/search/macros/select-deselect
\define select-all()
<$list filter="[subfilter<filtertext>!is[missing]!tag<workingTag>]">
<$fieldmangler>
<$action-sendmessage $timestamp=no $message="tm-add-tag" $param=<<workingTag>> />
</$fieldmangler>
\end
\define deselect-all()
<$list filter="[tag<workingTag>]">
<$fieldmangler>
<$action-sendmessage $timestamp=no $message="tm-remove-tag" $param=<<workingTag>> />
</$fieldmangler>
\end
→ didn’t work.
How can that be done?
Thanks
Stefan
That’s correct.
The $action-sendmessage does not accept
Use
<$action-setfield $tiddler="$:/config/TimestampDisable" $value="yes"/>
But this is a workaround, as you may forgot the turn it off!
I do not know any other solution now! Other users/developers may have better idea!
I submit a ticket for this on GitHub and have plan to push an update when 5.3.0 is available
Have you tried this setting?
You can turn it off by clicking on this button in the sidebar → Tools
(Perhaps, I did not understand your question correctly)
