What is new in Konverter 1.2.0

New in 1.2.0:

- **For web** replaces Compress in the tools wheel. One step: set the longest side (larger images are shrunk, smaller ones enlarged, or keep the original size), compress with the chosen quality, convert to sRGB and remove metadata. Saves `name-web.ext` or replaces the original (it goes to the Trash). PNG stays lossless.
- **Glass style**: the wheel carrier is now translucent. Switch back to the classic look in Settings, Style, Solid.
- **File size in the wheel centre**: while dragging it shows the number of files and their total size, and after For web how much space was saved.
- **TIFF and BMP** output formats.
- **Energy efficient**: drag detection runs only while the mouse button is held down, so an idle Konverter uses practically no energy.
- Fixed: HEIC photos from iPhone no longer get darker after compression (the HDR gain map is preserved).
- Compress is now part of For web. Its settings moved to the For web section of Settings; earlier values are not carried over.
