            Bug ID: 124323
           Summary: toggeling settings - e.g. threaded calculations - need
                    restart, UI unclear about this
           Product: LibreOffice
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Calc
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: newbie-02 at gmx.de

Description:
it's a similar thing with the user interface being unclear in when and why
changes of settings step in duty, as with formatting of cells, at what time the
formatting will affect the value in, or input to, the cell. 

(those are questions near philosophy, sorry, but there should be a philosophy
for a program, and it should be followed ... imho)

for a user interface being 'nice' to a 'normal simple minded user' i'd
recommend that changes as toggeling threaded calculations in calc 'tools -
options - libreofficedevcalc - calculate - cpu threading settings - enable
multi-threaded calculation' should either: 

- have instant effect, or 

- carry a hint 'restart required', and / or 

- have a signal indicating the status of the program (not the switch) somewhere
near the point the setting is done, especially if it's possible that the
checkbox deviates from the behaviour, 

(being able to check whether the setting is in effect with 'help - about
libreofficedev - and watch for "calc:" versus "calc: threaded"' is somewhat
'unintuitive' and requires some 'special knowledge') 

other behaviour is 'hoodwinking users'? (found that in deepl, not sure if it's
the right technical term)

even worse: 'help - about libreoffice' will instantly reflect changes in the
checkbox, while for being effective for the program a restart is required. thus
if touched the setting the user can't be sure how the real status is until the
next restart.  

reg. 

b. 

Steps to Reproduce:
change the mentioned setting, see not getting any hint that a restart is
required before it will be followed, 

either check other comments about this point or find a way to check whether the
setting is working or not, 

Actual Results:
checkbox changed, signaling in help changed, effect for calculations 'later', 

Expected Results:
either instant effect, or a hint on required restart, 


Reproducible: Always


User Profile Reset: No

handling of settings for openGL is not perfect but better than for threading,
