Linear MQTT Dashboard Customer Insights

1. Also importing / exporting is difficult / not working.Good features but buggy: crashes frequently, publishing from combobox widgets doesn't work etcI really like this app but it has some shortcomings.

2. And it shouldn't draw in duration has no income value (In fact it show last value in 1h mode, in 4h mode it work ok).Excellent app, just really needs a option for "End User Mode".

3. These are OK but when you see other fancy stuff around, man tend to wish even more 😁 P.S. JSON payload support would be nice tooVery Simplistic way of Controlling Mqtt Devices.

4. This is very good application, but this bugs push me to find another oneOne of the best MQTT client apps available.

5. How does it check if the mqtt server is down? When I stop my mqtt mosquito server it doesn't detect.

6. (I tried many mqtt apps but i like this one only after blynk)Great app, does what I need.

7. Is it possible to get app to check if mqtt server is connected every 5 sec and try to reconnect if not?Mostly good.

8. Also, the export format should be a plain text json file so large configurations can be modified/created on a PC.

9. Only thing that might need improvements are look and number of the widgets.

10. Add Lots of Device in Tabs, Import Export whole data including Settings.

11. The app also needs an RGB color wheel widget.In my opinion, the graph has a quite a few point.
