To auto build js and auto run tests use the following commands in seperate terminals.

npm run buildjs-watch

npm run test-watch

Fo sho:
|
|
||||||
- remember reading position / applied effects (per comic)
|
|
||||||
- offline mode via cache manifest
|
|
||||||
- firefox marketplace
|
|
||||||
- create onclose callback, show close button only if set
|
|
||||||
- trigger preload if requesting valid but not loaded images (can happen if network was interupted)
|
|
||||||
- loading and generally hackiness of pointer is buggy, fix.
|
|
||||||
- check for html5 feature support where used: diveintohtml5.org/everything.html or www.modernizr.com
|
|
||||||
|
|
||||||
Nice 2 have:
|
|
||||||
- remove image inhancement lag when navigating by pre-applying enhancements to other pages
|
|
||||||
- jump to page?
|
|
||||||
- make page draggable with the cursor
|
|
||||||
- enable menu items via config, allow for custom items
|
|
||||||
- split out classes into seperate files
|
|
||||||
- thumbnail browser
|
|
||||||
- refactor so we are not using all these loose shared variables and other nastyness
|
|
||||||
- use custom event emitters instead of hacky code
|
|
||||||
- properly bind 'this' so we don't have to keep using 'self'
|
|
||||||
- allow toolbar to be hidden on mobile (maybe show a small translucent button that opens the toolbar when clicked)
|
|
||||||
- enhancement progress bar
