I often use the LibreOffice Draw to prepare figures and diagrams which are later included in other documents (e.g., prepared with LaTeX).
That requires adjusting the size of the page to the size of the drawing.
Now it must be done iteratively, which is very inconvenient. Looking at the rulers I have to estimate the desired page size. Then I have enter the Format/Properties dialog box, enter the new "User" size of the page, close the dialog, check if the new size is correct (usually it is not), modify the size again in the dialog box... Typically the above must be repeated 3 or 4 times.
Other drawing tools, like Inkscape have a special option "Resize page to content".
A similar tool would be also very useful in LibreOffice Draw.
In case if its implementation is too difficult, it would be nice at least to be able to adjust the size of the page be dragging its edges, or corners in GUI (maybe after entering the special "resize page" mode).

Thank you in advance,
With best regards,
