Because of Bug 85538, cell referencing between different sheets is a nightmare in LibreOffice - under the default behaviour, when you set the reference to another sheet and then copy/move the sheet to a new file, the data gets messed up as the default behaviour uses relative reference.
This enhancement request is to request libreoffice by default will use absolute reference (i.e., add a "$" mark before the sheet name). This will retain the data when move/copy sheets, and also retain the "feature" of relative reference between sheets.
Steps to Reproduce:
1. New Calc, type 1 in A1 of Sheet1.
2. Add Sheet2, in Sheet2.A2 type in "=", then click Sheet1.A1.
formula shows as "=Sheet1.A1"
formula shows as "=$Sheet1.A1" (i.e., $ is added before the name of sheet).
There are many duplicates in bug 85538.
I think it is this bug which makes many of the advanced spreadsheet users (like me) mad when using LibreOffice Calc.
Unnecessary to submit yet another duplicate.
