For each of my layers, I have various attributes that I might be filtering on, like attribute
A < 1000 AND B > 300 etc..
Just like we can add an opacity slider to the legend, I want to be able to add sliders for the various attributes I am filtering on, without having to go into the filter screen and manually change the filter text.
I have seen this answer: Slider for non time attributes in QGIS
And while the hacky solution does work (use Time Manager), it doesn't really work if you want to have multiple sliders to explore your data.
I'm thinking of making something along these lines, but before I do that I figured it's such a useful feature that perhaps there already is a plugin that does it, or some other mechanism. I couldn't find it.
