This worked when the help file was its own "application" in the main
GUI. Would be no problem to generalize, but "for the moment" just note it
like this.

Cf. https://models.slf.ch/p/inishell-ng/issues/857/

-Move setting to 'preview' XML section because it exists from another setting now
-Remove obsolete documentation
-Clear status on TerminalView clear ("Process terminated" etc.)
-Remove useless _ from regex (it is checked by \w)
-Extend INIParser unit test with *::EXCLUDE example key
-Cosmetics
(Might want to clear settings with ./inishell -ce)

Of course, this means that "performant=true" must be replaced by
"pre-generate=false" for the same behavior.

'Alternative' panels. Better error messages.

Now for nodes where we know that the performance saving workaround
makes sense, we can explicitly set it in the attributes. By default,
all children are built. Result: E. g. GEO_HEAT will be filled correctly
even if it's not used because SNP_SOIL is FALSE (without having to state
that it should work in the XML).

Properly implement and document the newish workflow checkbox so it can be called by ID as the others. Minor cleanup in recent features; typos.

I did not see it being used anywhere, so if it is, please check if
something broke.

Implement a 'placeholder' property in Textfields and Selectors - if the text is empty this is displayed grayed out by Qt and can tell a user what to enter

XML. Also enable 'textmode' for some raw editing elements.

Set longlabel="true" to align a list of options containing names wider
than the standard column width.

Properly implement yesterday's 'buildall' option - this is actually really useful to decide between a safe and a performant build method (XMLs must be crafted more carefully and are less flexible for the latter but if it fits all is fine)

Allow to bypass performance savings in Alternative panel to always build all options. This is useful for Alternatives that are purely cosmetical (splitting up settings, showing/hiding elements)

single text field via a new 'textmode' attribute.

This is a cosmetic improvement for keys that do not have a default item
list (e. g. station names).
Some coloring consistence in the Dev help - but all of that doesn't
really fit together anymore.

The XML files had inconsistent case for the section names, this has been fixed. A mis-indenting has been fixed in help_dev.xml

Extend the TerminalView's context menu with a 'clear' entry. Add German translation for welcome text

Log INI errors in command line mode to console instead of opening a message box, and some readability.

Modify default checkbox labelling behavior: if a caption is given but no label - hide the label instead of displaying the key (most common use case). Some more XML

Fix doubled elements because of faulty XML references parsing with nested include files _and_ references. A little bit of the new meteoio.xml and some file cleanup for it

simulation. This is work in progress of course, but there's already a lot of information for
the interested user, and it should be more than enough for people knowing
INIshell v1. A few minor tweaks along the way.

(and to quit and for save/save as)

Add Selector help, Helptext tooltip help, don't transport Replicator help to children, 'Refresh' button for XML view
