You can increase the width of the columns by dragging the right border of the column header to the needed width. When you place the cursor at the right border you wll see an expand cursor indicating that you can change the width of the column.
For the moment the column width isn't saved with the view properties and will be reloaded when the view is opened again.
The default Area width is hard-coded in a client js file. I have updated it to 160px, which two times larger than current. I have prepared and attached the file, you should replace it in folder:
C:\Program Files (x86)\Telerik\TeamPulse\wwwroot\Scripts\wirejs\grid
If you want to change the width, you could search for the string - case"AreaName":return 160 and change 160 to what you prefer. Don't forget to clear your browser cache so the change can take effect. Unfortunately, the file will be replaced next time you upgrade TeamPulse and we will assist again, in case we haven't implemented saving column width.
