The option «legend positions» «top» and «bottom» doesn’t work (e.g. in pie chart). Also «center» option displays legend on the left.
You can resave the project only after adding/removing a viewer. If you just change the settings in the chart, change the chart size, or add a title, then the "Upload" button is grey out.
If you try to incorrectly enter formula in the filter properties then the page will stop responding (e.g. «=» instead of «==»).
When a network viewer is on the view, the «+», «-», «=» and arrows on keyboard always work to zoom in / zoom out / move around this chart, even when your mouse is on editing formulas. Thus, it is impossible to write any formula with an equal/plus/minus sign while a network viewer is in the project.
Tooltip in word cloud viewer always shows number of rows even if option «size column aggr type» is set up as a sum. Such unintuitive behavior leads to cases when bigger word will display smaller number in tooltip.
Pie chart can’t display a legend after reopening the project if it resides in the second page (dragged-and-dropped onto another viewer).
It is not possible to select colors for column elements via right click -> Current column -> Color coding -> Edit after reopening a saved project. There is no color selector in the pop-up window, which was when the project was initially created. A palette is automatically set and can’t be edited. If the palette has already been set before, then it can’t be changed - the popup will not open.
