[Lazarus] Install/Uninstall package form: "Do not install" & more

[Reinier Olislagers]

The Install/Uninstall package form has two lists:
a) installed packages (or those marked for installation. Caption above:
"Install"
b) available but not installed packages. Caption: "Do not install"

WHen I started using Lazarus, the "Do not install" caption made it
unclear that this is actually the list of available packages, and
Lazarus will not actually e.g. uninstall anything that is in that list
when you click Saven and rebuild IDE. (I know, I might be easily
confused, not RTFM etc).

1. Would it be a good idea to rename the caption to "Available"?

Some additional remarks/requests:
2. In additition to the red overlay for packages marked for
uninstalleation, and the green one for packages marked for installation,
perhaps a hint/tooltip could appear mentioned "Marked for
installation"/"Marked for removal" so people who don't know what those
icons mean are told? Alternatively I suppose mentioning this in Package
info in current state may also be considered.

3. Perhaps it's a good idea to have a search box for the left list
(installed packages) as well... depends on the amount of stuff you have
installed but it can be useful.

4. A long time ago I sent a reminder to package maintainers that it
would be a good idea to fill out the Description field of the package...
There's still quite some packages that have no info (aarrebase,
cocoa_pkg, customdrawn, demoidehelp, .... etc.)

Thanks,
