#### 1.3.3 The present situation

We have managed to create an editor that enables easy creation of mathematical
drawings, which was our main aim. VRR
offers a unique combination of these main
features:

**Geometric dependencies** which can be easily created by snap. In some
well-known geometric design tools, you can create much more complex geometric
constructions using projections and some other features that VRR
does not have.
But in VRR
you can create partially dependent objects which can then be
transformed, free them from dependencies or reorganize the dependency structure
completely – you have much more freedom if you want to create a not very geometric
image.
**TeX texts**, a crucial feature for mathematical drawings. Unlike other
editors, VRR
enables you to create and view the resulting text instantly,
you can even apply transformations to it. The whole image can be exported to PostScript,
which is also a necessity for mathematical drawings.
**Various graphic features** – they are not very many and could be
improved vastly in VRR
. VRR
does not support fancy stroke and fill styles,
gradients, ... as vector graphic editors usually do. However, such features are usually
not used in illustrations of mathematical papers; for that, VRR
's graphic capabilities
are quite sufficient.

We can now see almost infinitely many possibilities how to improve VRR
, which
features to add ... Thus we could keep ourselves occupied for the next ten years.
Regrettably, we need to submit VRR
and work on some other things as well.
Anyway, we are going to maintain VRR
in the future; we enjoy the users'
feedback that we already have and hope that our work will be useful.
