-# Hard to reproduce bugs
-
-* add PRINTFs to observers, there is something wrong with save as
-* sometimes, when the background layer is in a strange state:
-  * two layers, hide background, the extra cel/brush preview isn't visible in the mini-editor
-  * timeline: can move background
-* does lock alpha work correctly?
-* does onscrollchange notification calls onscrollchange notification?
-* random clicks on toolbar crashes the program
-
-# Tasks
-
-* onion-skin-bug.ase: See frame 2 with onion skin, there is a bug
-* update copyright year of source files (automate this in with a script)
-* Remove Image::getPixelAddress(), it shouldn't be public and almost
-  everywhere we should use iterators for images. Also get/put_pixel_fast
-  and ImageImpl::address() are dangerous.
-* Warning message when we open a file that is already opened
-  (show an option to create a second view, or maybe this should
-  be forbidden).
-* New sprite with palette of the clipboard
-* Ctrl+Shift selection should copy and snap axis
-* "Duplicate sprite" should copy the "Background" layer as Background.
-* Fix problem applyToTarget() can throw (it's called from other thread)
-* Shade drawing mode.
-* Improve status bar indicators (show origin of selection in floating state).
-* Export to sprite sheet: if the file we're using is .ase, select .png by default
-  (and then the latest used extension).
-* Fix problem with export sprite sheet when the cel has negative pos
-* MovingPixelsState: Add undo information in each transformation step.
-* Add IntEntry class in src/ui/ with spin-buttons.
-* Add color swatches bar.
-* Sort palette entries.
-* Add "Remap" button to palette editor after a palette entry is modified:
-  This button should apply a color curve to the whole sprite to remap
-  old indexes to the new positions.
-
-# Refactoring
-
-* Make one level of layers (folders should modify only timeline/UI)
-* Convert doc::PixelFormat to a enum class
-* Add doc::Spec with width/height/channels/ColorMode/ncolors
-* Convert doc::LayerIndex -> typedef int doc::layer_t;
-* Replace doc::Palette::getEntry() with doc::Palette::entry()
-* Remove LayerFolder, replace it with an array of layers
-* Add new "level" into Layer class
-* Refactor src/file/ in several layers.
-* Use streams instead of FILEs and create load/save tests with streams.
-* Destroy modules/gui.h.
-* Convert update_screen_for_document in an event from contexts or
-  something similar.
-* Use a class to wrap calls load_window_pos/save_window_pos.
-* Command::loadParams() should be called one time when the command
-  params is read from the XML file, not each time the command is
-  executed. For this all commands must be got from the CommandsList,
-  then cloned, and finally filled with params.
-* About Signals/Slots: Add some field in slots to avoid disconnecting
-  them from dead signals.
-* editors_ -> MultiEditors class widget
-* all member functions should be named verbNoun instead of verb_noun or noun_verb.
-
-# Old issues
-
-* fix bilinear: when getpixel have alpha = 0 get a neighbor color.
-* fix sliders in Tools Configuration, they are too big
-  for small resolutions.
-* rewrite palette-editor to edit multiple-palettes.
-  * fix quantize (one palette for all frames, one palette per frame)
-  * pal-operations (sort, quantize, gamma by color-curves, etc.);
-  * complete palette operations, and palette editor (it needs a slider
-    or something to move between palette changes)
-  * drag & drop colors.
-* if the Tools Configuration dialog box is activated, Shift+G and
-  Shift+S keys should update it.
-* add two DrawClick2:
-  * DrawClick2FreeHand
-  * DrawClick2Shape
-* see the new Allegro's load_font
-* review ICO files support.
-* add "size" to GUI font (for TTF fonts);
-* layer movement between sets in animation-editor;
-  * add all the "set" stuff again;
-* fix algo_ellipsefill;
-* view_tiled() should support animation playback (partial support:
-  with left and right keys).
-* fix the fli reader (both Allegro and Gfli): when a frame hasn't
-  chunks means that it's looks like the last frame;
-* talk with Elias Pschernig, his "do_ellipse_diameter" (algo_ellipse)
-  has a bug with ellipses of some dimensions (I made a test, and a
-  various sizes have errors).
