Sorting of input layer Layers in Processing "multiple inputs" widgets

Original Redmine Issue: 17327
Affected QGIS version: 2.18.13
Redmine category:processing/core
Assignee: Victor Olaya

In Processing Tool Box Modules such as Gdal>Misc>Merge, Gdal>Misc>Build Virtual Raster or OTB >Image Manipulation>Images Concatenation the order of loaded raster layers in the Layers Panel is not correctly transferred to the input images layers list (Mutiple selection) of the Processing Toolbox modules. The order of the layer is random and cannot be changed which makes these modules useless.

This is pretty much duplicate of #25026 but this is more general.

Is indeed a real issue: in the multiple inputs widgets there is the need to allow sorting of layers and the sorted list then transferred as it is in the command being executed.

This should be fixed in master - can you confirm?

I just checked: is not completely fixed. In the multiple input widget you can as a fact d&d the layers to reorder them but:

• having also arrows would be more intuitive for the users

• d&d only kind of works: if in the list you d&d a layer over the name of another then one of the two is removed from the list

Should we change the status of this to "open", or open a new ticket (or close - I haven't checked if Giovanni's last point is still a problem)?

Hi guys, if you are using outputs from several uses of another algorithm (perhaps a smoothing algorithm or gdalwarp), and you drag them around to change the order, is there any way of knowing which one is which?
See #25824

I guess the arrows thing should be a feature request, the second issue seems fixed.
