here are some thoughts on the program interface.
In the menu there are a number of menu items, which all have only one entry "Show ... Window". Perhaps one could summarize this in the menu "View" or in a seperate tab under "Preferences".
The menu item "Preferences" could be introduced into the menu bar.
"Preferences - New QSO" contains the lines "Enable auto search on QRZ.COM" and "Ignore QRZ.COM QSL Info. Other settings to QRZ.COM can be found at "Preferences - connection Program "Internet.
Perhaps it would be good to consider all the settings to QRZ.COM together.
If it is planned to display more information in the window "New QSO", or to take this together in groups, this window might be provided with a range that is divided in tabs. For example, "QSL tab" "Awards" tab"...
This could also make the names more detail. For example, QSL Send> Via Bureau "instead of"QSL_S" "B".
I just like user interfaces designed very well. Therefore, I find the CQRLOG very well. In any case, I use the program exclusively.
Sometimes we can see that resolved in other logbook programs, one or the other in the optical arrangement of the elements is clear. Perhaps you could add a release to re-factor of the surface.
However, since this all looks different, for me that is not crucial.
I hope you can understand the text. Otherwise, please complain to Google Translate, HI.
