- 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
- Reference list dialog further optimized to fit 1920x1080 @150% or 1024x768 @100% screens
- re-imported translation file (to fix incorrect letters in language names like "Русский")
- upgrade to DevExpress 22.1 libraries
- added write support for dtv_cmdb_2.bin
- File / Information no longer shows duplicate program number warnings for negative numbers (-2 is an allowed dupe for dtv_cmdb_2)
- fixed Sony unit test (Sky option channels are now counted as TV and not data)
- lots of documentation around Philips lists
- working configuration for ChannelMap_100 variant with cmdb files (redordering confirmed, hide/lock/rename/favorites are best-effort)
- pressing the "Del"-key on the keyboard no longer deletes a channel when a text editor is open
- dragging a file (or something else) from outside ChanSort over the ChanSort window no longer creates an error
- opening a file containing a read-only channel list now shows the original numbers
