Re: [libreoffice-users] Calc SLOW with filtering large data set

I realized this morning that the version I installed was the "fresh" 
release and not the "still" release.  I did that because it was at the 
top of the download page for the installer and was the only one that 
showed on my browser screen (I didn't think to scroll down because 
convention seems to be to present the current safe version at the top 
and provide access to potentially unstable versions via more obscure 
links).  Seems to me it would be wise to hide the "fresh" version and 
present the "still" version at the top of the list.

I am downloading the v.5 "still" release and will test that on the new 
computer.  I'm expecting it to work faster.

I also noticed that the 6.0.1 release is missing the memory management 
option under the Tools|Options menu.  I'd thought perhaps I could speed 
up the filtering of the long file with memory management but there was 
no option for memory management that I could find.  I don't know if 
that's intentional or a bug, but I thought I should mention it.  Again, 
that is in v.6.0.1.
