Hi,
I haven't found another feature request regarding paradata so I opened this entry: I know of javascript to include in a question for collecting paradata. However, that seems unwieldy. Especially in times when an increasing number of users respond on mobile phones, an adaptive design would be highly useful to reduce dropout rates. Also, for debugging an issue within Limesurvey sometimes the information on the browser and mobile OS is necessary for the LS-support to find the bug more efficiently. Therefore, I recommend including toggle buttons or similar in a separate paradata menu.
