user-friendly now.

## Tables
Important improvements in table handling.
Improved drag & drop mouse operations to move table data.

# Calc
Improved selecting cells which contain hyperlinks.
n MM:SS or [MM]:SS or MM:SS.00 or [MM]:SS.00 pre-formatted cells a two digit \ 
groups input like 12:34 is now accepted as minutes:seconds value instead of the \ 
usual hours:minutes:00 value; to force the usual hours:minutes:seconds input on \ 
such cells enter three digit groups like 12:34:00.
Improved scalability of formula-groups computation on CPUs with large number of \ 
cores by potentially threading multiple independent formula-groups together.
Implemented a parallelized version of super scalar sample sort algorithm to \ 
speed up sorting. This is now used in pivot-table creation where some sorting is \ 
required.
Shading of columns/rows headers is removed; the headers are drawn flat now.
Deleted a 15 symbols limit to password length for XLSX files.
Performance improvements.
Full-Sheet Previews.

For edit mode, a context menu "Execute interaction" was added.
