Everytime I open the Jabref, the left column is too wide and the entry details on the bottom shows, leaving the main window very small.

When I drag and resize it, and close the bottom entry's details part, it looks good until I quit and reopen the program again. It seems that the UI failed to remember my adjustment. I have search the settings and found no place to set.

Caption: Too wide on the left, bottom part is annoying, the main part is so small. It occurs every time I start the program.
