Something i noticed:
Why does Bodhi have an online appcentre with a few applications while other distro's have a software centre which contains a lot more applications?
If you look, for example, to a distro like Elementary OS, their appcentre/software centre is packed with a lot of available applications, easy to install and remove. To browse all applications/packages i'm using Synaptic and/or the terminal to install certain packages/applications.
Is it possible to have an appcentre or software centre like Elementary OS in Bodhi instead of having an online appcentre which is far too narrowed down regarding the available applications?
Well, it written in The wiki.
The AppCenter features a great selection of excellent software, all of which will run without problems on Bodhi Linux. Either search for the software by name in the Search box, or select from the listed categories to see what’s on offer.
It not supposed to be exhaustive, but an "elite" picks, best apps for different kind of needs.
and Synaptic just one console line away, for exhaustive list. Better yet, add GetDeb and PlayDeb Repo.
