Improvements

Minor improvements to the user experience.
It is now possible to modify the load factors of an automatically generated Load Combination. The Load Combination will then be converted to a manual Load Combination automatically.
Added a 'Fix'-Button to automatically add an SLS Combination when the program warns that the user has not added any SLS Combinations for the Crack Width calculations.
Added a 'Fix'-Button to automatically adjust the height of B-bars when they are taller than the Cross Sections height.

Bug Fixes

Fixed a visual bug where points could incorrectly appear as maximums/minimums on the charts.
Fixed a bug where the program would occasionally create log files in the folder of the currently open file.
