[Feature Request] More options for Sysstat

[bluzrevolusion]

About ''Sysstat'' I would like to request some simple additions:

-In the ''CPU'' type, when you select ''Use frequency'' would be great to get that information on text

-In the ''Memory'' type, to select what type of memory usage to show: bufer, applications, cache; if I only select the applications type, only show the memory usage by the applications, if I select all, show all the memory usage (like now is)

-When you put the pointer over the graph of memory give the information not only in percentages, give it in amounts too, example: 500mb.

-The option for choosing to show the information in bars (doesn't show the previous usages, only the usage of the moment)

1. SysStat would gain if Disk Space indicator also would be available

2. Would also agree that total amount matters (RAM, Disk Space) and

3. there could be realtime permanent text over colorful bars, like cpuload widget does.

Atm custom command plugin can be used for disk space, examples here https://github.com/lxqt/lxqt/discussions/2179
