MKVToolNix (64-bit)

What's new in this version:

Backend:
- Updated to 7z 19.00

Code:
- Recompiled with Lazarus 2.0
- Various fixes

File manager:
- Drag and drop extraction results in hiding the main form, consistently to behavior from Extraction and Archiving screens

Extraction and archiving:
- Extraction: "Smart new folder" option improves and replaces "Remove redundant directory" option
- if the new folder contains a single object (file or folder), content is copied outside and the extra folder is removed (removes extra folder layer and preserves original names of archived folders), if copying the content outside the new folder fails, the content is kept in the new folder
smart extraction is meant to guarantee that a single item is extracted, to avoid flooding target directory of multiple unexpected items, and that no unneeded level of directory nesting is added
- Improved GUI feedback during preliminary steps of archives conversion and "TAR before" procedures
- Improved GUI feedback running option to delete original sources
- Improved information shown about running archiving / extraction tasks

Windows & linux installers:
- (Windows) Extraction from context menu results in a single queue consistently with behavior from Extraction screen, and consistently with archiving from context menu
- (Windows) "Extract here (to new folder)" context menu entry now enforces creation of new folder level (disable smart new folder)
- (Windows) "Extract here (smart)" context menu entry (new) enforces using smart new folder option
this item is now flagged by default during installation in place of "Extract here (to new folder)"- can be changed during installation
