How to use an installed scanner?

Allright, some windows opened along that track -but is this all, this path to be used every time I would want to scan something?

When I used a Gentoo-version of Linux together with a Brother MFC device, I had an icon "scanner" to click on to get going.
I would expect kind of the same thing also under ubuntu.

Expanding on the issue, I also had icons for Evolution and Open Office under Gentoo -but not yet under ubuntu.
Would appreciate a crash course also for such settings.

To submit proposals of improvement, you have to submit a "Bug".
So people who write software can see it.

For the scan, a lot of software (like Gimp) are able to call directly XSane, which is the library (or daemon?) which manages scanner.

Regarding the icons you were inquiring about, you can drag the icons for the requested applications to your desktop or to the panel. For example, click Applications, then Graphics, then click and hold on XSane Image Scanner, and drag the icon to your desktop or panel.

Here we go again:

I've been using my PC under Linux/gentto for quite some years.
Here, I had icons on the desktop to click on when I wanted to:
-use Evolution
-write text and
-scan a document

Then, days ago, on the same computer, I shifted to Linux/ubuntu.

Here, if possible, I would like to come back to the same kind of
convenience I enjoyed previously.

My remaining questions are:
1. Is this possible? and
2. How?

If the answer is negative, the replies already provided now allows me to
access Xsane with the path provided.

My more general question would finally be:
3. How to make buttons/icons of the described kind appear on the
desktop?

Thanks delance, that solved my question.
