My initial check used the Google Play Store and Avant led all over the place as a keyword search, same again with Avant Browser.
Any app that could be tested for its app creator ought to lead back to the Avant website anyway.
That is another way to search for apps by checking Google Search for that website as well.
The Avant Browser details explain about a portable version ie some zip file being involved.
It helps to test complex apps on the DS 1.5 box rather than the 1.2.
There are complex web browser apps, each with quality features that make us switch from one app to another.
The same applies with saved or downloaded files eg long paused OK action on the image leads to Save Image? Or open in new tab?
The web browser may allow a different download path rather than the internal storage card itself.
From then on, accessing a File Browser app or File Manager style app can lead to various actions like delete or move or rename, ie cut leads to a later action elsewhere for past file or files here.
I recently saw a HUSH HUSH promotional offer for the iMedia Blaze 9" tablet, soon to expire:

Tablets can do extra things rather than the DS set top boxes.
But it's the testing of more than one app for a known purpose that gets us more involved in how we can develop particular features with other apps, too.
So it is with the PC and web broswers and I've tried the Enigma web browser and TheWorld web browser and Slimbrowser. Only when I got a 160GB Windows 7 PC was there loads of storage to test even more.
