Use interactive filter to choose Categories and Evalution , and display evalution slider columns.
If Evalution is only one selection, such as New ideas ,and then display slider columns, Otherwise hide slider columns. Bcz different evalution has different slider columns.
Reduce number of views: In some docs, the number of views is so large that the filters and conditional formats on all those views take too long to calculate even if no individual column in the table is slow. This is not usually an issue for docs with several dozen views but we’ve seen docs with much higher numbers of views where the views themselves took 10-20 seconds to recalculate each time the data in the doc changed.
