Created attachment 108815 [details] screenshot to make clear what I mean - create a new custom fit - use e.g. as fit function this: exp(b*sin(a*x)+c - click the button parameters result: the 3 fit parameters appear in a window that one cannot move. At least the windows should be moveable and resizeable but in my opinion the preferable way is to list the fit parameters in a table widget below the f(x) field automatically. This keeps the information in the side widget, one saves a button and the user has everything directly in sight. Attached is a screenshot to make clear what I mean.

> Attached is a screenshot how MagicPlot does it. Noe that MagicPlot displays the fit function using its parameters immediately. This helps a lot because this way one can see if the start values for the different parameters make sense.
This requires several changes in the current implementation. We will address this in the 2.6 release.
With the latest commit the parameter list is now part of the dock widget which now also supports folding of option groups. This should fix this issue.
