other CMake projects using the MidasConfig.cmake file produced during the Midas
installation.

MidasConfig.cmake might at some point get included in the standard Cmake installation (or some add-on). It will then reside in the Cmake system path
and you don't have to explicitly know where this is. Just the find_package(Midas) will then be enough.

I agree that those two things are problems, but I don't see why it is preferable to leave the MidasConfig.cmake in this "broken" state. For us
problem 1 is less of an issue, becaues we run "link_directories(${MIDAS_LIBRARY_DIRS})" in the top CMakeLists.txt and then just link against "midas",
not "${MIDAS_LIBRARIES}". However, number 2 would be nice, to not manually hack in target_include_directories(target ${MIDASSYS}/mscb/include),

I disagree with the proposed change to scale the HV current for a "nice" display. If values are scaled, the axis should be
scaled in the same way. Otherwise people might read the current from the plot, look at the axis, and again get the wrong
value (the factor of 25x you mention). Sure you can hover with the cursor over the graph, and see the right value, but think

We are using the new history formula as a quick way to convert signals from sensors to actual physical values (for example Voltage->Temperature, Voltage->relative
humidity

One addition I would be in favour of is to remove the "Order" and replace it with drag&drop handles, because this is what people are more
used to today. Only the old guys like us remember the /etc/init.d/xx_yy scheme where one uses an integer number in the file name to
determine an order.

A requested change in the history logging system has been made today. Previously, history values were
