This has annoyed me for a long time .;never really cared to post .
When drag/drop a phrase from the container onto the keyboard .;an indicator shows the root key where the phrase should be positioned .
It will however always be positioned incorrect .
say phrase 1 ..lets drop it on key D ----> it will be dropped on c ..
Say phrase 2 ...we want to drop it on E , it will positioned on C# ..always next to the previous phrase ..
