- channels can also be swapped now be directly selecting two rows and clicking on "swap"
- swapping mark (strike through) is now automatically removed after swapping
- swapping is now recognized as a change and will prompt to save the list on exit
- added "Pooling=False" parameter to all Sqlite connection strings to prevent open file locks after closing the connection and to avoid extreme delays when using CloseAllPools()
- C# code refactoring "using var" instead of "using ( ) { }" where possible
- replaced misuse of "FileLoadException" with a custom LoaderException to handle file loading issues with better continue/fail logic
- removed "Save As" and replaced it with "Convert list" menu item that shows information on how to use a reference list instead of direct conversion
".BIN" and ".BIN" to lowercase ".bin".
- Philips: Removing a channel from a list is no longer possible (because it is not supported by the TV's import).
When saving a file, all unsorted channels will be placed at the end of the list.
- support for Philips Repair\mgr_chan_s_fta.db lists is now read-only. Files can be used as a reference list,
but modifying them won't be possible.
- added round-trip unit test for all loaders to check reordering channels and favorites, saving and reloading
- internal code clean-up regarding different favorite list modes (none vs. flags vs. ordered per source vs. mixed source)
