automatic positioning of scroll bar on selection of filter

Feature Requests
1

hello,
I make this feature request in the follow up of different UI improvements.

context: User using paraview particularly with pvstates or python scripts.
when we load a pvstate or run a python script on the paraview client, the hole pipeline will be created automatically, things that should be shown on the render will be shown etc etc.

issue/situation for this improvement to take place: hey i see this specific thing displayed on the render viewer, what it is?/which filter it is? i would like to apply a new filter to it and keep working from there, but i dont know which one it is. So, (at least on how i do it) i select a element from that rendered filter and would scroll thought the pipeline browser to ‘see’ which one it is. this works but when we have a pipeline of more than 12 elements (which is… always?) it becomes annoying quite fast, is the selected filter upper on the browser? lower?

proposal: Improve the current behavior, so when the object is automatically selected on the pipeline browser (current behavior) the scroll bar of the pipeline browser will scroll to place the selected filter in the middle of the current viewables filters on the browser.

iiuc, you want the pipeline browser to scroll to show the current active source when it changes (using python of otherwise), is that correct ?

If so, this is quite easy to do and a very good idea !

more or less!
les say, I have a bunch of filters shown in the renderviewr, and i dont know which is which on the pipeline. eg. the blue sphere:

what I currently do, I use select blocks thought hit a random element of the blue sphere as shown, and it will select it on the pipeline browser, so then i can apply lets say transformation to it. aslo i did it intentinally as you can see the sphere i selected is not in the part that i ‘see’ currently on the pipeline, i need to scroll down to find which one it is:

the FR is about, hey not only select it but move the scroll bar automatically so ‘sphere 29’ is on middle of the pipeline elements i can see.
