Garuda Rani is a great all around tool, but I noticed that it currently lacks tooltips explaining what each option within the app does.
Since Garuda Rani provides a wide range of system maintenance, tweaking, and configuration options, it would be really helpful for new users if tooltips briefly described the purpose and function of each option.
Garuda-Rani is indeed a great tool, and it would be nice if tooltips were available everywhere. However, that depends on manpower and available time. As far as I know, Garuda-Rani is being developed by one person: @dr460nf1r3
He does great unpaid work for Garuda in his spare time (and not only him, but others as well). However, he is a student with limited time.
I am sure, anyone with the necessary knowledge is welcome to get involved and fill in the gaps.
I’m in fact a professional developer since a few months 
What I could do is exposing an easy way to add descriptions to options, so people could add them via Transifex (our translation service).
@vigr have an example of options that are unclear to you?
While I’m familiar with most of the options, there are a few in the System Settings modules that I’m not familiar with - for example, options like “Use IWD instead of wpa_supplicant” or “intel-undervolt” etc.
To clarify, I’m referring specifically to options under System Settings modules, not the other sections of Garuda Rani. Although a quick Google search can usually explain these options, it would be nice to have all the information easily accessible within the app itself in the form of tooltip.
Congratulations 
And sorry for making you so small
