Nek5000 solves in high-order (N can ba larger than 10).
As far as I know, vtk now supports high order format (at least up to N=10).

Paraview's current Nek5000 reader turns high order into linear. It actually turns a Nth order polynomial element into (N+1)^d linear Cells.

So, I wonder if you can support nek5000 format further.
(Maybe ask user to use high order or not when reading the file)

Thanks!

With tons of colormaps imported into ParaView, the Preset editor looks very crowded and less manageable. There is just a "default" preset group option to select favorite colormaps. Would be great to add more groups so that colormap presets can be categorized more easily.

ESTABLECER COMO USO DE MONITOREO Y LOGRAR VER IMAGENES Y TRAZADOS DE DATOS DE MULTIPLES ORIGENES SEAN ESTOS RELACIONADOS AL MISMO CASO O MULTIPLES .

I've created several custom plugins for Paraview, along with some python macros that chain some of the filter commands together to make the user experience more friendly and efficient. It would be nice if you could enable a macro(s) to be automatically loaded into Paraview along with a plugin.

Update the render view or layout display whilst exporting animations to show the current frame.

Display the estimated time remaining when exporting animations.

Add an opportunity to change GUI language

I like the ability to create a custom viewpoint, but one can only give them names in the configure viewpoints menu. The main toolbar just shows 1, 2, 3, and so on. It would be great for those numbers to be replaced with the viewpoint name, e.g. Arctic Ocean.

I find very annoying and tedious to change fonts one by one in many different places when the same font is wanted everywhere.

For example, while producing two line charts where I didn't want to use the standard fonts I had to change the font manually 10 times (2x legend, left axis label, left axis, bottom axis label, bottom axis).

Would be thus a very nice feature to set the fonts once for all everywhere if needed.

Import georeferenced image as a flat surface in 3D or texture

Enable exporting the pipeline result to Fbx file with the color,filters and legend.

Enable customization of the 2d Gliph with a custom user's image

ParaView is a rather complicated 3d scientific visualization software. It's difficult for beginners to understand the basics from a book.
I suggest adding some basic short video tutorials to help people understand the key components of the software and include more examples (maybe the most common questions from the support forum).

.off files are great to read and write.

Reader for .dx files

add the possibility to read results from Ansys-CFX CFD code.
