I'd strongly recommend dropping the extra "quality of life" improvements</blockquote><div> </div></div><div style="font-size:12.8px" dir="auto">As Nyall and others have suggested I have trimmed down the proposal to focus on essential features. Thus I reworked the proposal accordingly, and shifted the planning to allow more time to handle the amount of new features and complexity.<br></div><div style="color:rgb(80,0,80);font-size:12.8px" dir="auto"><div><br></div><blockquote style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Something to consider in your UI designs is that there's two different "types" of expression based values for parameters</blockquote></div><div style="font-size:12.8px" dir="auto"><pre style="text-wrap: wrap;"><span style="font-family:'arial',sans-serif">An easy fix in the UI would be to have a drop down to select either value input or expression input and have the button to open the editor on the right of the widget.<br>I went with this solution, and updated the mockup accordingly.

I will make sure to include the Gdal algorithm in test cases during the GSoC. Now if I understand correctly, custom parameters are not currently reflected when used in the context of the modeler (see for example the parameter 'Additional creation options' in gdal algorithm is simplified to the default widget for string). How we handle them will also help solve the issue for non-trivial input like the the "Fields Mapper" or the "Multiple Input Layer". I checked in other software neither FME nor Unreal Engine(with a HashMap) display this directly in the user interface. I think we can safely let them inside the properties windows of the node/algorithm for now.<br></div><div style="color:rgb(80,0,80);font-size:12.8px" dir="auto"><div><br></div><blockquote style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Care would need to be taken in handling existing models. I think the new interface would have to be opt-in</blockquote><div> </div></div><div style="font-size:12.8px" dir="auto">I agree with you that we need to take extra care of existing models, however I am not that keen to have the interface as an opt-in option. I am afraid of the additional burden to maintain two systems alongside. I'd rather spend a bit more time polishing the backward compatibility. For instance, while the more natural flow will be left-to-right in the new interface, the top-to-bottom will still be possible, and we can also play with the collapsed version of nodes, I think we could end up with a rather similar layout for most existing models. <br></div><div style="color:rgb(80,0,80);font-size:12.8px" dir="auto"><div><br></div><blockquote style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Do you already have a mentor planned for this work? </blockquote><div><br></div></div><div style="font-size:12.8px" dir="auto"><div>I don't have a mentor planned yet.
