Changeable height of the log

[Korb]

Currently, the maximum height of the field for displaying the work log is 236 pixels including the header, and it cannot be made larger even if the height of the application window allows it. I suggest adding the ability to move the border separating the upper and lower parts of the window. That is, to do it as it is, for example, in the qBittorrent application or many email clients.
